## Question:

The ping-pong ball has mass M. If it is struck with the velocity shown, determine how high h it rises above the end of the smooth table after the rebound. The coefficient of restitution is e. M = 2 gm , a = 2.25 m , e = 0.8 , b = 0.75 m , θ = 30 deg , g = ${ 9.81 m/s }^{ 2 }$, v = 18 m/s
