Still remember your basic physics? If so, try these.

[BehindEnemyLines]

I found these in a book, and it's been awhile since I last took physics.

1. A ball is dropped at rest into a well. You hear a "splash" 3.00s later after release. What's the depth of the well? Assume velocity of sound = 336 m/s.

2. A train travels b/t 2 stations. The train never reaches its max cruising speed b/c the stations are only 1.00 km apart. During rush hr the engineer minimizes the time interval "delta t" b/t 2 stations by accelerating for a time interval "delta t sub 1" @ a rate of "a sub 1" = 0.100 m/s^2 & then immediately braking w/ acceleration "a sub 2" = -0.500 m/s^2 for a time interval "delta t sub 2".

Find the minimum time interval of travel "delta t" and the time interval "delta t sub 1".

3. Requires knowledge of calculus II I believe. The accel. of a marble in a certain fluid is proportional to the speed of the marble squared, and is given (in SI units) by a = -3.00v^2 for v > 0. If the marble enters this fluid w/ a speed of 1.50 m/s, how long will it take before the marble's speed is reduced to half of its initial value?

Right... you happen to find these in a "book" (your textbook) and would like us to solve these problems (for you).

Try doing your own homework moron.

 

Ok, let's brush up on your basic sexual education.

1. What is a penis and what is a vagina, and which do you possess?
2. There are 4 boys and 3 girls in a room, one goes home alone, is that you?
3. When your father asks you to engage in sexual relations, do you consent?
4. The vagina looks most like .. a.) flower b.) cantaloupe c.) italian sausage d.) I don't know what a vagina is.

This next question may require experience with women.

5. What is your favorite position?

Calling somone a "moron" ie "a very stupid person" isn't nice. I tried, I failed, and I asked for help, and I get called for not trying and a "moron". If every teacher is like that...

If you don't want to solve it, then you can always give hints, tips, etc....I'm not asking for line-by-line solutions. There's no need for name calling and sarcasm and inappropriate sexual humor.

Le'ts not forget this site is frequented by young kids.

it's not as much as you asking for help as you pretending its not your hw and that you just happened to find these questions. And also you gave no indication you actually tried. most people that ask for hw help usually explain their thougth process and people try to point out where their logic went wrong. but instead you're just expecting us to give you answers. well fvck that, go do your own damn work.

You're still a moron. I'm contemplating adding you to my list. We'll see how many people reply with yes's and no's, or how many PM me with yes's and no's.

Moron.

People probably would've helped you if you had told the truth right away and just nicely explained that you don't grasp the concepts you're learning. Sure there still would've been a few people who would call you stupid, but they're conceited and don't matter. There are lots of nice people around that would've helped you had you told the truth.

Wow, I didn't even take physics yet and I can do the first one. I've taken Chemistry for a year and am taking organic chemistry and I managed to do my h.w, why can't you?

 

[BehindEnemyLines]

I'm trying to review for physics next quarter. That's the truth. I can't say much if you don't believe me.

I managed to get a little further for #3.

#3. If a = -3.00v^2 and the speed the marble enters the fluid is v = 1.5 m/s, then the acceleration Am = (-3.00 * (1.5m/s)^2) = -6.75 m/s^2. So Vi (initial speed) = 1.5 m/s and Vf (final speed) = .5Vi =
.5 * 1.5m/s = .75 m/s

==> Vf = Vi + at ==> t = (Vf-Vi)/a = (.75m/s - 1.5m/s)/(-6.75m/s^2) = .11s. But that ans. doesn't match with .22 sec. Any thoughts where I did wrong on this one?

It mentions calculus maybe required. I tried finding the integral of a = -3.00v^2 ==> V = -v^3, but I don't see how that equation plays in this problem.

28.595 seconds for the first question, I think.

Did I read that you "asked for help"?

<Not entirely serious>
I hope you never have to ask for help if you're dying..."sir, I was just wondering if you remembered your basic biology...if there is this knife in my side, what should I do to stop the bleeding?"
