A block of mass m=2.20 kg slides down a 30 degree incline which is 3.60 m high. At the bottom, it strikes a block of mass=7.00 kg which is at rest on a horizontal surface in the picture. If the collision is elastic, and friction can be ignored, determine (a)the speeds of the two blocks after the collision, and (b) how far back up the incline the smaller mass will go.

Problem: A 0.500kg block attached to a spring with the length 0.60m and force constant k=40.0 N/m is at rest with the back of the block at point A on a frictionless, horizontal airtable. The mass of the spring is negligible. You pull the block tothe right along the surface with a constant horizontal forceF=20.0-6N.
