A block of mass 2.30 kg slides down a 30.0 circ incline that is 3.60 m high. At the bottom, it hits a block of mass 7.65 kg that is at rest on a horizontal surface. (Suppose a smooth transition at the bottom of the incline.)
(i) When the collision is elastic, and friction can be ignored, find out the speed of the block having mass 2.30 kg after the collision.
(ii) When the collision is elastic, and friction can be ignored, find out the speed of the block having mass 7.65 kg after the collision.
(iii) Explain how far back up the incline the smaller mass will go.
