Question

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 his hands.
• C. increase the rate of change of momentum.
• D. decrease the rate of change in momentum

Answer 1

Answer: (B), (D)

decrease the rate of change in momentum

Explanation of the correct option

(B): Reduce the force exerted by the ball on his hands

1. A goalkeeper in a football game pulls his hands backward after holding the ball shot at the goal.
2. This enables the goalkeeper to decrease the change rate of momentum and reduce the force exerted by the ball on their hands.
3. Therefore, the goalkeeper is trying to reduce the force exerted by the ball on his hands.

Hence, when a goalkeeper in a football game pulls his hands backward after holding the ball shot at the goal. This enables the goalkeeper to reduce the force exerted by the ball on his hands and decrease the rate of change in momentum. Hence options (b) and (d) are correct here.
