## Question:

The ball is dropped from rest and falls a distance h before striking the smooth plane at A. If it rebounds and in time t again strikes the plane at B, determine the coefficient of restitution e between the ball and the plane. Also, what is the distance R? Given: h = 4 ft , c = 3 , g = ${ 32.2ft/s }^{ 2 }$ , t = 0.5 s , d = 4
