oh, that is a good point. Sorry, I didn't notice that; in that case, you are correct. And my bad, had it been the force, the answer is actually 0.0406, not 0.406. But all is well that ends well!
well, i think you are close. The Normal Force is equal to the force going down, that is, mass times acceleration, because this is in one dimension. That means that you actually should do Normal Force = 9.3 * 9.8. Then you divide 3.7 by the answer, which should give you 0.406.
if you think about it, sciences like chaos theory applied in physics have barely scratched the surface. We've discovered the potential science involved, but we just haven't yet come up with astounding results. We will though. I'm sure.
oh i thought you got it. Sorry. You know that x displacement is 250 ft, and y displacement is 0. If you plug that in, you'll find you have a system of two equations with two variables--initial velocity and time. I'm sure you can solve from there. :wink:
close. You forgot that the y equation has acceleration due to gravity, so that's \frac{-9.8}{2}t^{2}.
And is that how I'm supposed to do math equations here? Cuz I am relatively new (I signed up earlier, I just never used it till now).
The only proof I can think of off the top of my head is the apple and archer proof; the question is here: http://www.alexpleasehelp.com/online/problems/arrowapple"
To make it a proof, you basically have to show that as long as the arrow is fired at the apple at its starting position, and...
So, I'm looking at colleges and whatnot, and I know I want to be a doctor of some sort, so I am going to do pre med, but I am also really into physics. The plan is to hopefully go to a college that has a good premed classes and advice, but also get a physics major at that college. First off, is...
