Actually, the previous answer is incorrect.

The best way to solve a problem like this is to list what you know:

t = 3 sec
vsound= 340 m/sec
A(gravity) = 9.81 m/s^2

trock = time for rock to travel
tsound = time for sound to travel back up
trock+tsound = 3 sec.

What do the sound and the rock have in common? They both travel the same distance. We want to isolate the distance here.

Drock = 0.5aTrock^2
= 0.5*9.81*Trock^2

Vsound = Dsound/Tsound.
340 m/s = Dsound/Tsound.
Dsound = 340 m/s*Tsound

From here, we can equate Dsound and Drock.

0.5*9.81*Trock^2 = 340*Tsound

If Trock+Tsound = 3, then Tsound = 3-Trock. Sub that in.

0.5*9.81*Trock^2 = 340*(3-Trock)
= 1020 - 340Trock

Bring it all to one side:

4.905*Trock^2 + 340*Trock - 1020 = 0.

Look familiar at all? What if we substitute Trock with just plain t:

4.905t^2 + 340t - 1020 = 0

It's a quadratic equation! Now you can plug it into the quadratic formula:

t = (-b+/- sqr(b^2-4ac))/ 2a

t = (-340+/- sqr(340^2-4(4.905)(-1020)))/ 2(9.81)

The two answers I got were about -72 and 2.88. Obviously, the stone can't travel back in time, so it must have fallen for 2.88 seconds.

Now we can substitute that answer back into the distance equation for the rock:

Drock = 0.5aTrock^2
= 0.5*9.81*2.88^2
= 40.69

So, your well is 40.69 m deep.

Always check your answers to make sure they make sense. If the well was 1020 metres deep, that's a kilometre deep! Doesn't make much sense, does it?

Please, please, PLEASE try to understand what your mother is going through. Don't make it any harder on her by complaining.

I've been living on my own for 4 months now with my fiance away on military work. I'm working 60 hrs per week, taking care of the house and the dog. I don't have kids, or I'd be taking care of them too. I am worn out. It is so hard to do everything while you're lonely and missing the person that you love and care about!

Your mom isn't keeping you around to make you miserable. She's keeping you around because she's lonely.

You can't change your parents' relationship. What you can do is make things easier on your mom. Ask her how you can help. Maybe pick up a few extra chores, or spend a few nights a week with her doing fun things.

Try to be forgiving, because your mother is going through some tough stuff. It's not easy to go it alone.

Your story is so inspiring! I'm at the beginning of an 80 lb weight loss journey, so it's nice to hear from someone who is having success!

First tip: www.myfitnesspal.com is my life saver. You can track your calorie intake and exercise (it's really easy), there's great forum support where people exchange tips and recipes, and you can keep track of your progress.

I don't have favourite recipes so much as favourite foods.

If you have a barbecue, say hello to your new best friend. If you don't, go get one! Even a cheap one will do.

I grill EVERYTHING. I grill meat, vegetables, even fruit!

Favourite veggies on the grill: asparagus, red peppers, portobello mushrooms, red onions. To grill them, just brush them with a tiny bit of olive oil and a sprinkling of salt.

If you cut pineapple into chunks and put it on bamboo skewers, it grills up really nicely. Makes a great dessert, or you can serve it with chicken or shrimp.

Some of my favourite snacks are celery with peanut butter and raisins, popsicles made with Crystal Light or sugar-free Kool-Aid, and Ugli fruits (really low-cal... they're a cross between a grapefruit and an orange). Peak Freans also makes a delicious coconut lime cookie that I love.

Remember, it's every bit as much about how you eat as it is how much you eat. Keep track of your portion sizes.

Your boyfriend is being controlling. Period. That is not acceptable. You are a human being, and you should be able to make your own choices so long as those choices don't adversely affect someone else. He can't forbid you from doing it. You deserve better than that!

Your boyfriend needs to man up and TRUST you. This is something you have to tell him. Stop hiding what you're doing or where you're going. If he complains or threatens, so be it. You can't go through life with this guy looking over your shoulder and controlling your every movement!

Ha ha... thanks :D

It just bugs me when you try to help someone, take your time to research an answer, and then they give you a really nasty response.

Actually, red kool-aid can turn your pee red. The other flavours not so much.

So can eating anything with red food colouring, beets, blueberries and boysenberries.

My thinking, and I will stress that I am NOT a doctor, is that if it was an on-going problem, it would happen more than once a month. If his kidneys were failing or if he had an infection, he would be fairly consistently peeing blood, like once or twice a day for a week.

A suggestion would be to have him drink a bunch of red kool-aid and then watch the colour of his urine. If it changes after that, then that's likely the culprit. If he cuts out the red kool-aid and doesn't eat any beets, and this is still happening, then he should definitely be checked out by a doctor. Try to avoid unnecessary expense, but watch his health.

EDIT:

Wow... you think you're helping people on this website, and then they go and prove that you're wasting your time.

To respond to your "feedback", and I use that term loosely, seeing as it was more of an illiterate rant.

http://www.wrongdiagnosis.com/symptoms/red_urine/causes.htm

"Causes of Red urine:

The following medical conditions are some of the possible causes of Red urine. There are likely to be other possible causes, so ask your doctor about your symptoms.
Blood in urine
Certain foods
Beets
Borscht (beet soup)
Certain medications
See also causes of blood in urine (hematuria), red urine, or darker urine
Glomerulonephritis
Urinary tract infection"

Red urine can be caused by ingesting certain foods. Red Kool-Aid is one of them. Blue Kool-Aid is not one of them. Your urine won't change colour from eating a red apple, but it could change colour by eating beets. See the difference? The red is a dye (either natural or synthetic) that is not processed by the body. Urine carries the remainder out of you, because you don't want it to accumulate. So your mom is wrong, so maybe she's the one who should "gesh go to school".

You indicated that he was a drinker of red Kool-Aid. I took this to mean that there may have been a connection there. Us Advicenators can only work with what we're given.

You didn't say it was happening several times a month, and occuring randomly. You said [sic] "hes been peeing blood but it happens like once a month". If you had included the vital information that it was dripping randomly and happening several times a month, or included any other symptoms (like pain, maybe?), then I would have given you a totally different answer... "GO TO THE HOSPITAL NOW!"

As for your request that I "gesh go to school", I'm a 3rd year engineering student. Is that good enough?

If you were that concerned, you'd be at the hospital with your guy right now instead of b*tching at the people on the internet whose help you enlisted.

It's people like you that make me consider withdrawing my assistance. There are people out there who legitimately need and want help and are grateful for the assistance they receive, and it's people like that who make me keep going.

Grow up, and learn how to be grateful.

Oh, and maybe you should take your own advice, and "go to school". You might learn how to punctuate a sentence properly.

I see nothing wrong with getting engaged young. I was 19 when my fiance proposed. However, we have had the benefit of some experiences that it sounds like you haven't. I do agree with you that marriage is forever, so we've made our decisions based on that principle.

First off, and some may disagree with me, I believe that you should have had at least one big fight before getting engaged. Why? Marriage is forever; for better or for worse, right? Well, how do you know what the worst is unless you've actually had to face it? If you haven't at any time questioned your relationship because of a big issue AND overcome that problem, then the "worse" can come up and bite you in the bum later when you are irrevocably attached.

There's a big difference between spending time at each other's houses and actually living together. Sure, you know if she's messy, and she knows that you still have your Star Wars bedsheets (just examples, obviously). Do you know how she is with money? Does she know how you are about dividing chores? It really takes some time with living together to work through the real issues. Things like dividing housework, or dealing with financial shortages, or sorting out your daily schedules.

My suggestion is to take your relationship one step further by living together before you get married. Get an apartment together. See how you handle the division of finances (a huge issue on its own), the stress of living with someone else, and the overexposure to each other. You both need to be bombarded with each others' bad habits. Chances are high that it will work out, because it looks like you have all your other ducks in a row.

Long engagements are a great idea. I've been engaged for 2 years now, and it'll be 3 by the time I'm married next August. During that time, my fiance and I have overcome huge obstacles. It gives you a chance to get in a married mindset without taking that huge leap all at once. It also gives you a little time to get older (because you do change as you get older, and you'll need to get used to each other).

So yes... propose away. It sounds like you've thought things through. I had people tell me that I was too young to be engaged. Don't ever let anyone convince you that you're not ready. Not everyone can be measured by the same standards. I've met 45 year olds who are less mature than some 17 year olds.

Well, you've got three choices.

1) Stay at home.

2) Earn more money.

or

3) Find a roomie.

Obviously, you don't want to do 1), or you wouldn't be asking about it.

If you don't want to live with someone, then you need to earn more money. Pick up another job. Pick up extra shifts. Ask for a raise. Find a job that pays better. Do any or all of the above! You can't change the landlord's rules, but you can change your situation.

If you don't want to sacrifice your life to live alone, then you've got to get searching for a roomie. You've mentioned that you don't have many friends... try looking at postings online. See if anyone out there is looking to share a 2 or 3 bedroom apartment. You'll be interviewed, so you can pick someone who is more to your liking.

Another thing to do is to try looking for apartments in people's homes. Sometimes independent landlords will be more flexible. Craigslist and Kijiji (if you're Canadian) are great websites for this.

The Miami Beach area is fantastic. I spent 2 weeks there last year with my family. The beach is so huge that it doesn't get full, and it's always warm there (unlike Daytona Beach, which is also quite nice).

Old Navy has some really cute solid polos, and they're really inexpensive.

Okay... this could get lengthy.

When a lot of hot air rises, the moisture it contains will condense into water droplets, which will freeze when they get high enough. They start to fall then, and collide with water droplets on their way up. This creates static electricity (like when you rub a balloon on a sweater).

Static electricity will build, but as soon as the thing that is charged comes near something that isn't charged, it will discharge. You know when you rub your feet along a carpet and then shock someone? That's the static electricity discharging from you to them.

Lightning is like a giant version of that static shock.

When lightning strikes, it releases a ton of heat. This heat makes the air around it expand and move outwards really fast. The hot air collides with surrounding cool air, and that makes the noise.

The reason why you hear the thunder after seeing lightning strike is because sound travels much slower than light.

It starts raining harder when there's lightning because a ton of warm, moist air is getting lifted during a thunderstorm, and more water droplets are created.

Hope that sort of explains things!

I've seen AC/DC before. Great live show! You'd never know they were old enough to be my parents...

Comfort is the bottom line when you go to a concert.

Don't wear anything that you'll need to tug on to keep it in place. No short skirts, no tiny shorts, no shirts that ride up. You want to be having fun, not worrying that you're giving an eyeful to the rest of the audience!

Shoes should be flat and closed-toe. No heels, unless you want a broken ankle, and no sandals unless you want broken toes.

As for style, stick to casual, dark colours. You don't want to dress too girlie for this crowd. Jeans and a cute black top would do nicely.

Don't do anything overly elaborate with your hair and makeup. You'll probably end up all sweaty and disheveled anyhow.

Make sure to listen to tons of their music in the time leading up to the concert to get you in the mood! Learn the words where you can, because it's always more fun when you can sing along.

As you've seen, in this day and age you need some sort of education to get a job.

The one way to get your resume looked at is to start with continuing your high school. That shows that you have initiative and want to better yourself.

Thing is, even with just high school, you'll end up with a job, and nothing more. What I would aim for is a career.

There are tons of programs out there that can get you educated quickly in a field you'll enjoy, and will help you with financing. Think about what you're passionate about. Not everyone needs to be a surgeon or a lawyer; everyone does need to be happy in their line of work!

With the weed, have you actually explained to him why it's a big deal? Or have you thought about why it's a big deal to you? Maybe he just thinks you're trying to control him. For instance, I'm on my fiance's back about smoking weed because it could lose him his job with the army. If you haven't given him another reason other than "I don't like it when you do it", then he's going to rebel. Men are like children that way :P. If you can come up with a good reason why it hurts you when he smokes weed, tell him. Otherwise, you're going to have to keep that to yourself.

Personally, I think that it's not a big deal for your guy to have a social life outside your relationship, whether that is with girls or with guys. My fiance is free to go to other girls' houses if he wants to. Most of my friends are guys, and I'll spend time alone with them at my house. He trusts me.

If you don't trust him to do that and not do anything stupid, then there is an issue. There is a real problem with your relationship if you cannot trust him enough to be out of your sight with another girl.

You have to calm down a little bit. You not trusting him will hurt things in the long run. Think of a time when you've been accused of something you didn't do. Hurts, doesn't it? I don't know about you, but when someone does that to me, it makes me want to do the thing I've been accused of, because there's no point in being punished for something I haven't done!

By controlling what your boyfriend does more, he's going to push more. The more you rein him in, the more he's going to run when he can.

My advice is to ease up on the poor guy. Relax, and stop thinking the worst of him. Let him have fun without worrying "Oh, what will SHE think?". Let him know what some rough boundaries are (i.e. no sexual stuff with other women, or keep weed smoking to a minimum) for your comfort. Then let him go. Chances are, he'll prove that he's worthy of your trust. If he isn't, then dump him, because nobody needs a guy who lies to them.

My fiance is in the military. He goes off for months at a time. He's told me the stories about married men screwing around like crazy when they're away from their wives. I know I can trust him, though, so I don't worry about him being away from me. I know he's a good guy and will do the right thing, even when he's propositioned by a stripper (LOL!)

You're young. This relationship doesn't have to be forever. If he's not the person that you want him to be, let him go and find the person that you want. There's no forcing someone into a different mold. If you can't accept his differences, then it won't be a happy relationship.

Harsh, but true.

Sounds to me like the media scare-mongering is getting to you!

If you were the leader of a country, you wouldn't spend millions on weaponry without testing them first, right? That's like if the US bought a ton of warplanes but didn't do test flights.

North Korea was testing bombs. The main issue (why everyone was up in arms... no pun intended) is that they were testing them in Chinese airspace.

On a smaller scale, that's like if you bought a gun and were test-shooting it through your neighbour's backyard. Kinda threatening, but nobody gets hurt. Your neighbour would probably get angry and tell you to stop.

Many countries have nuclear weaponry. The US has more than any other, but for some reason wants everyone else to give up theirs.

Just look at it this way: Canada and the US have not been friends forever. There was a time in history when you had nuclear-tipped missiles pointed over our cities for "intercepting aircraft". Especially considering that you guys were all twitchy from the Cold War, and feeling a little gun-happy, that made us nervous, but we didn't stop being your allies.

North Korea has a long history of being bullies. They're a noisy little country, but they're all talk. If they were to attempt to bomb the US, they'd be squashed so fast their heads would spin. They're under careful surveillance. The moment they took one step out of place, they'd be suppressed. So no need to worry.

Something that might make you feel better (or at least give you a laugh) is watching Team America: World Police. It's great for giving a little perspective to the situation :)

My fiance and I got a trainer last year.

For us, it cost $100 per session. You can spread it out over a year, though. You can generally only buy sessions in packages starting at 16 and working your way up to 72 or so.

I had a good experience. He showed us how to use the machines, gave us nutritional advice, and kept tabs on our progress. He led us through one heck of a workout (I was always buzzing with adrenaline at the end of it!) and it was always different every week. I was feeling stronger and healthier!

The negative: Following everything he said to do, working out 5 days a week, eating carefully... I didn't lose a single inch or pound. I've actually had better success with WiiFit!

Trainers are great for motivation. They make working out more fun, and more productive. It is a huge financial commitment, though.

There is no way that a girl can force a guy into sex, unless she's holding his family at gunpoint.

Getting another woman pregnant while he's supposed to be faithful to you is unforgivable! Find a guy who won't screw around on you and then lie to you.

I would have to argue with some of the others. An engagement ring is not necessary at all. Sometimes, there isn't money for things like that, so the guy will propose without one. I have one, though :)

The wedding band is exchanged on your wedding day. Some people wear both afterwards (I plan on it... no way I'm putting away my diamond!), some only wear a band. My mom wears neither, but she wears the ring my dad gave her for their 15th anniversary. It's all personal choice.

An eternity band is a ring set with diamonds the entire way around. It's often given on a special occasion in the relationship (like an anniversary milestone).

Favourite quote from my high school physics teacher:

"Never get a woman a diamond ring. It's just an overpriced rock with a refractive index of 2.42. Get her something useful instead."

You've received some odd advice here.

I work for a call-answer service. I do nothing but answer phones for real estate companies, so I know what kind of stuff you deal with.

How to be taken seriously? Don't cry. Don't complain. Do your job, do it well, and do it with a smile on your face. If you handle your job in a mature fashion, people will respect you more. If you start complaining or crying, people will see you as the one who can't handle the easy position.

As for them respecting your position... if you are hanging out with co-workers, mention a particularly tough call, and how you solved the problem. Don't complain about it, though. Just bring it up as if describing an accomplishment.

Try to model yourself after employees that you respect. Being respectable is the only way to gain that respect!

The other two have covered budgeting pretty well, so anything I say at this point is going to be repetition. There are just a few points that I want to address...

What are your plans for college? Do you have a full ride scholarship? Are you prepared to have serious student debt if not? How are you going to handle the expenses of school when you can't work full-time?

I live in Canada, and tuition is subsidized here. Here's a breakdown of what I pay for a year of school:

Tuition: $7500-$8000 per year.
Books: $1000 a year
Lab fees: $300 a year.

So you're looking at a cost of about $9000-$10 000 a year. I'm in engineering, which is an expensive program, but you'd be looking at at least $6000 more per year.

Keep in mind that earning full-time while going to school is not easy, or even doable depending on what program you're doing. So even if you can get your tuition and books covered, you'll have to cover your living expenses as well on a part-time salary.

Is your boyfriend willing to help you pay for school, and support you while you cannot make full-time wages? It sounds like a silly question, but he may resent having to support you.

Do you want to be put in a position where you have to depend on your boyfriend? I've been there: it sucks. What if he decides to withdraw his support? What if you guys break up (a distinct possibility once you've moved in together)? Then what will you do?

I know I sound super-negative, but you have to look at all these things before making a decision like this.

Oh, and as for taking away things that you've paid for... you live under your mother's roof, and allowing you to have these things and freedoms (even if you've paid for them) is a favour she's doing for you. She is totally within her bounds to take things away from you if you are misbehaving. Just my "old person" perspective.

My Personal Forum

My name is Amanda and I'm 26 years old. I'm currently studying electrical engineering. Armed with a fairly odd sense of humour and a sunny outlook on life, I'll take on just about anything. I'm also cussedly stubborn, which has its ups and downs. Things get tough sometimes, and I've never been one to run from it.

In my last 8 years with Advicenators, I've gone from honours student to failing out of university (and getting back on top again!), from single to married, from tenant to homeowner.

Until lately, I have been struggling with a diagnosis of bipolar disorder and OCD, which had basically ruined my life and taken just about everything from me. I'm thankful every day for every experience I've had because of this ordeal, because it's helped to make me who I am today. Things like that really make you appreciate what you do have. Now that I'm back in work and school and starting to become myself again, I couldn't be happier. I credit Advicenators with saving my life back when I was a teenager, which is a big part of why I'm still here.

I won't necessarily give you the answers you want to hear, but I'll always be honest and do my best to help.
