If the... 1 answer below » A basketball traveling with the velocity shown in the figure strikes the backboard at A. If the coeffi- cient of restitution for this impact is e = 84, 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.

For the normal – tangential coordinate directions, as shown in schematic diagram, it is considered that: Calculate the velocity in tangential direction before hitting the backboard. ft v = (24xsin 40°) sec ft = 15.42 sec Calculate the velocity in normal direction before hitting the backboard. V. =-(24x cos 40°) ft/sec =-18.38 ft/sec Calculate the velocity in tangential direction after hitting the backboard. v' = (24xsin 40°) = 15.42 ft/s
