Question

A goalkeeper in a game of football pulls his hands backward after holding the ball shot at the goal. This enables the goalkeeper to

• A. exert a large force on the ball
• B. reduce the force exerted by the ball on hands
• C. increase the rate of change of momentum
• D. increase the inertia

Answer 1

The correct option is B

reduce the force exerted by the ball on hands

A goalkeeper in a game of football pulls his hands backward while holding the ball shot at the goal. This increases the time span for the momentum to be reduced to zero which reduces the force, as we know that force is change in momentum per unit time.
