Question

Explain why when catching a fast moving ball, the goal keeper should draw his hands backwards

Answer 1

Explanation:

while catching a fast moving Cricket ball a fielder in the ground gradually pulls his hand backwards is a moving ball in doing so the fielder increases the time during which the high velocity of the moving ball decrease 20 the acceleration of the ball is decrease and therefore the impact of catching a fast moving ball is also reduced stop suddenly when it is high velocity is decreases 20 in a very short interval of time does 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 Meher the palm of the fielder

or

a cricket player moves his hand backwards on catching a fast Cricket ball to prevent injury to the hands

reason

a fast moving Cricket ball has a large is Momentum the momentum of the ball has to be reduced to zero in order to catch

when cricket player moves his hand back the time taken to reduce the momentum of the ball 0 is increased

due to more time taken to stop the ball the rate of change of momentum A ball is reduced enhance a small force is exerted on the hands of face show the hands of player do not get hurt

is a cricket player stop the fast moving bus suddenly than last momentum of the ball will be right is 30 in a very short time due to which the rate of change of momentum of ball will be very large which will exert a large impact force on players and causing the injury to his hands.

conclusion

to prevent injury to his hands always a cricket player moves his hand backwards on catching a fast cricket ball
