Question

Calculate the retardation and the retarding force.
Why does a cricket player move his hand backward while catching the ball?​

Answer 1

Answer:

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.

Answer 2

Explanation:

because the momentum of the ball is much more higher than the cricket player who is going to catch the ball (momentum is equal to product of mass and velocity and momentum of ball) so to catch the ball he have to overcome 5hat force so he just move his hand backword when he catches the ball.

hope this will help.
