A ball rolls down a hill from rest and collides with a block on wheels at the bottom. The block has a mass which is 4 times larger than the mass of the ball. Calculate the direction and velocity of the block and ball after the collision, if they were (a) elastic, or (b) perfectly inelastic. Please show the answers in terms of g and h.
(c) how much of the kinetic energy is lost in the elastic collision of part A?
