I'm not sure, but until someone better at physics responds, this'll probably tide you over:
When the water is going forward, I guess it's pushing the hose/person holding it backward
the momentum going forward is .6kg*25m/s, and you get the force by taking the change in momentum over the...
I'm trying to decide if it's worth my time to make my undergraduate GPA super high
My cumulative won't get much higher than 3.2 even if I get 4.0 for the next two years, so I won't be able to get into any honors societies, and the only reason I can see to bother temporarily memorizing every...
Don't worry; I figured it out on my own
Man, this site is so crappy for getting help on anything specific
Well, it's no big deal
If someone comes across this in the archives or something and wants me to tell them how to solve the problem, they can drop a line to killamarcilla@bigpen.us
So I should have taken ds/dr ds/dtheta instead of the other way around to get the right sign, and I should have taken r dr dtheta rather than just dr dtheta, but even when I do that I still get the wrong answer
hmm.. I can't figure out how to get this one right without just using the...
Yo guys, I'm stumped on how to parameterize this surface and then compute an integral over it
I'm supposed to compute \int\int_S \vec{r} over the surface formed by the x-y plane and z=4-(x^2+y^2), but I don't know to put it together and do it
(No matter how you work with x and y, z will...
The math isn't that tough
Well, it's not tough for me, and it's less tough than what you need for a fancy physics degree and way less tough than for a math degree
I think I'm probably just going to end up being a professional programmer since I'm so much better at it, but I'll be a...
0hh0, how intriguing
At the very least, his advice about appreciating and preserving life, liberty, and the pursuit of happiness warrants some merit
Stupid mad cow disease.. although I guess that I shouldn't be eating beef anyway, if I want to lose weight
It'll probably be 2005 by the...
OK, I think I have the formula:
y = mx+b*ln|ve^(bt)-v+1| -ln| (1-v)/e^(bt) + v / ( P*e^(r*t) )
.. oh, wait, that's just a bunch of useless gibberish
sorry
Man, I was pretty convinced that people will always be fine and the environment won't get totally screwed up, but I was reading a biology textbook earlier today and it sounds like we're screwing things up pretty nicely
All sorts of cropland is being destroyed by overusing it and not letting...
Well, my friends.. if I get banned, know that it was fun (and I'll be back with a different name)
So a Physicist, a Mathematician, and an Engineer are all asked to prove that all odd numbers are prime
The Physicist says "1 is prime, 3 is prime, 5 is prime, 7 is prime.. Given the...
