• B. Reduce the force exerted by the ball on hands
• C. Increase the rate of change of momentum
• D. Decrease the change in momentum

Answer 1

Answer: (B), (D)

Decrease the change in momentum

Explanation for correct option:

Option (B):

1. After holding the ball, the goalkeeper pulls his hands backward to slow down the rate of change of momentum while increasing the time.
2. Because force is directly related to the rate of change of momentum, this allows less force to be exerted on his hands.

Hence, option (B) and (D) both are correct.
