A 5 gram cart is released from rest 1 meter from the bottom of a frictionless, 30 degree ramp. The cart rolls down the ramp and bounces off a rubber block at the bottom.
This question comes with a graph of force vs. ms (meter seconds). I can't show the graph, but I can describe it:
It resembles a triangle pointing straight up with two legs of equal length (like the shape of the letter A). The base has a width of 26.7 (ms), and the peak is at 200N.
