A coach knows it is vital that the volleyballs be fully inflated before a match.
(a) Calculate the impulse on a spiked 0.123-slug volleyball when the incoming velocity of the ball is – 11.5 ft/s and the outgoing velocity is 57.3 ft/s.
(b) Using physics terms, explain what would happen to the outgoing velocity and the impulse on the ball if it were not fully inflated.
