A block of mass m = 2.10 kg slides down a 30.0° incline which is 3.60 m high. At the bottom, it strikes a block of mass M = 6.90 kg which is at rest on a horizontal surface, (Assume an elastic collision, and ignore friction.)
(a) Determine the speeds of the two blocks after the collision.
lighter block m/s
heavier block m/s
(b) Determine how far back up the incline the smaller mass will go.
