Homework Help: Determine the speed of the smaller mass

  1. Mar 3, 2005 #1
    A block of mass m = 2.30 kg slides down a 30.0° incline which is 3.60 m high. At the bottom, it strikes a block of mass M = 7.10 kg which is at rest on a horizontal surface, Fig. 7-41. (Assume a smooth transition at the bottom of the incline, an elastic collision, and ignore friction.)
    How can I determine the speed of the smaller mass and the greater mass after the colision. This is really confusing me :confused: . please help

    In an elastic collision, momentum and kinetic energy are conserved for the system.

    So from this I should be able to make a simultaneous equation?
