A basketball traveling with the velocity shown in the figure strikes the backboard at A. If the coefficient of restitution for this impact is e = 0.57, determine the required distance h above the hoop if the ball is to arrive at the center B of the hoop. Carry out two solutions: (a) an approximate solution obtained by neglecting the effects of gravity from A to B and (b) a solution which accounts for gravity from A to B. Neglect the diameter of the ball compared with h. 24 ft/sec 42 A in. in. B 15"- Answers: (a) Neglecting gravity: h = (b) Accounting for gravity: h= h i 23 15
