A goalkeeper in a game of football pulls his hands backwards while 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

decrease the rate of change on momentum

D

Both B & C

Text Solution

Verified by Experts

The correct Answer is:
D
The goalkeeper pulls his hands backwards after holding th ball to decrease the rate of change of momentum by increasing the time. By doing this, less force is exerted on his hands, (Force is directly proportional to the rate of change of momentum).
