A quarterback throws a pass which is a perfect spiral. In another words, the football doesn’t wobble, however spins smoothly around an axis passing via each end of the ball. Assume that the ball spins at 8.8 rev/s. In addition, the ball is thrown with the linear speed of 16 m/s at an angle of 59° with respect to the ground. When the ball is caught at the similar height at which it left the quarterback's hand, determine how many revolutions has the ball made while in the air?
