Don't spam and don't delete my question Physics Class 9 Chapter force and laws of motion - Explain too - Q is
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 balls on the hands (c) increase the rate of change of momentum (d) decrease the rate of change of momentum
Answers
Answer: (b) reduce the force exerted by the ball on hands and
(d) decrease the rate of change of momentum
After holding the ball, the goalkeeper pulls his hands backwards to slow down the rate of change of momentum while increasing the time. Because force is directly related to the rate of change of momentum, this allows less force to be exerted on his hands.

i am 13
and I am from Lucknow, Uttar Pradesh
well in which class you are studying?
Answer:
The goalkeeper pulls his hands backwards after holding the ball to decrease the rate of change of momentum by increasing the time.
By doing this, less force is exerted on his hands as force is directly proportional to rate of change of momentum.
