Problem 17.2 A girl throws a ball at an inclined wall from a height of 3 ft, hitting the wall at A with a horizontal velocity vo of magni- tude 30 ft/s. Knowing that the coefficient of restitution between the ball and the wall is 0.85 and neglecting fric- tion, determine the distance d from the foot of the wall to the point B where the ball will hit the ground after bounc- ing off the wall. B d 3 ft 65°
