Homework Help: Physics1

Posted by Jon Routh on Tuesday, November 17, 2009 at 9:52pm.

Two blocks are initially held at rest on 30 frictionless ramps . The 4 kg block is 1.25 m from the base of the ramp and the 3 kg block is 5 m above the base of the ramp. The two blocks are then released and slide down the ramps and onto a frictionless horizontal surface. The two blocks collide elastically with each other and then move backward up the ramps again. The 4 kg block comes to a stop 3.09 m up its ramp. How far up the ramp does the 3 kg move before coming to a stop?
