Ah, I think I've got it now. I just hope I won't confuse this with anything else on my test tomorrow. :P Thanks!

The problem: The acceleration of a particle moving back and forth on a line is a = (d^2)s/d(t^2) = (pi)^2 cos(pi)(t) m/sec^2 for all t. If s = 0 and v = 8 m/sec when t = 0, find s when t = 1 sec. My work: (d^2)s/d(t^2) = (pi)^2 cos(pi)(t) ds/dt = (pi)^2 sin(pi)(1) + C ds/dt =...

I just recently started studying physics about a month ago, so I'm not too good at it yet. Anyway, here's the problem: When a certain object is 100 meters above the surface of the Earth, Earth's attraction for it is 10 Newtons. In order for Earth's attraction for the same object to be only 5...
