Two elastic balls of masses and are placed on top of each other with a small gap between them. The balls are dropped on to the ground with the bottom of the lower ball at height above the ground. The lower ball has a radius and the upper ball has negligible dimension. (a) Up to what height the ball of mass will bounce above the ground ? (b) Does the result obtained above violates the low of conservation of mechanical energy?
