Answer: Using the third equation of motion, we get V initial = (2gh)(1/2) (As the ball falls a distance h above the next step.)
Also, V final = {2g(h-d)}(1/2) (The ball rises a height (h-d) above the step it strikes.)
Using the formula of coefficient of restitution,
we get
(h-d)/h=e2 ( the velocity of steps will be zero)
Rearranging,
h/d=1/(1-e2)
