Hi guys (and girls), I'm kinda new to these forums. What I mean by that is I haven't yet posted anything, but I have been lurking around for a few weeks. Anyways, I'm stuck on this homework problem. A 500 g cart is released from rest 1.0 m from the bottom of a frictionless, 30 degree ramp. The cart rolls down the ramp and bounces off a rubber block at the bottom. The figure shows the force during the collision. I have setup my force diagram and found the following information: Fnet(x): 2.45N Velocity at bottom of ramp: 3.13m/s Time to reach bottom of ramp: 0.64s Unfortunately, I don't know what to do next. This problem is very elementary I know, but all help will be appreciated.
