Question

Question 3
A goalkeeper in a game of football pulls his hands backwards after holding the ball shot at the goal. This enables the goalkeeper to
(a) exert larger force on the ball
(b) reduce the force exerted by the ball on hands
(c) increase the rate of change of momentum
(d) decrease the rate of change of momentum

Answer 1

By moving the hand backward, the impulse applied by the ball on the hand decreases as the time period of slowing down the ball increases. Hence option B is correct.
