A block of mass m710 kg slides down a 30 degree incline, Ask an Expert

Academics

A block of mass m=7.10 kg slides down a 30 degree incline which is 3.60 m high. At the bottom, it strikes a block of mass M= 3.00 kg which is at rest on a horizontal surface. (Assume a smoothe transition at the bottom of the incline, an elastic collision, and ignore friction.

Determine the speeds of the two blocks after the collision.
