Problem
A cricket ball of mass 0.15kg is bowled towards a fielder with a speed of 30ms−1. The fielder catches the ball and brings it to rest.
(a) Calculate the initial momentum of the ball.
(b) Determine the change in momentum of the ball during the catch.
(c) If the ball is brought to rest in 0.020s, find the average force exerted by the fielder on the ball (magnitude only).
(d) To limit the average force on his hands to 300N, what minimum time should the fielder take to stop the ball?
(e) Suggest one practical way by which the fielder can increase the stopping time while catching, and briefly explain how it helps.
