coefficient of restitution

If the tennis ball of Prob. 3/239 has a coefficient of restitution e = 0.8 during impact with the court surface, determine the velocity Ï…0 with which the ball must be thrown downward from the 1600-mm shoulder level if it is return to the same level after bouncing once on the court surface.

Prob.239

Tennis balls are usually rejected if they fail to rebound to waist level when dropped from shoulder level. If a ball just passes the test as indicated in the figure, determine the coefficient of restitution e and the percentage n of the original energy lost during the impact.
