Question

3)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 hands.

c)increase the rate of change of momentum.

d)decrease the rate of change of momentum​

Answer 1

Answer:

B) reduce the force exerted by the ball on hands.

Explanation:

While catching a fast moving cricket ball, a fielder in the ground gradually pulls his hand backward with the moving ball, In doing so, the fielder increases the time during which the high velocity of the moving ball decrease to zero. Thus, the acceleration of the ball is decreased and therefore the impact of catching the fast moving ball is also reduced.

If the ball stopped suddenly then its high velocity is decreased to zero in a very short interval of time.

Thus, the rate of change of momentum of the ball will be large. Therefore, a large force would have to be applied for holding the catch that may hurt the palm of the fielder.
