Question

Explain why does a cricket player moves his hands backwards, while catching a fast cricket ball.

Answer 1

The player moves his hand back to increase the time interval, as the greater time will reduce the force being applied from the ball , protecting his hands from any severe damage.

Answer 2

A cricket player lowers his hands while catching the ball :

We know , F = dp/ dt

If a player does not lower his hands while catching the ball, the time to stop the ball is very small. So, a large force has to be applied to reduce the velocity of the ball to zero or to change the momentum of the ball . When a player lowers his hands, the time to stop the ball is increased and hence, less force has to be applied to cause the same change In the momentum of the ball. Therefore, the hands of the player are not injured.
