The problem is that a ball is released from y=10 m and must hit a target 40 m away which is 6 m high. The ball is released and bounces with its height dropping by elasticity squared (E^2) each time. The problem then states that it is possible to caluculate the number of bounces using the range x...

I'm not sure how to find the initial velocity of a ball that is released from a height y and bounces through a distance x. The ball has an elasticity E and radius R but I don't know an equation that relates these and the number of bounces to the ball's initial velocity.
