Problem
A cricket ball of mass 150g is moving horizontally towards a fielder at 25ms−1. The fielder brings the ball to rest.
(i) If the ball is stopped in 5.0×10−3s when the hands are kept rigid, calculate the average force experienced by the hands.
(ii) When the fielder moves his hands backward, the time of contact becomes 2.0×10−2s. Determine the new average force.
(iii) Find the ratio of the force in part (i) to that in part (ii) and interpret your result in terms of safe catching technique.
