State why cricketer move his hand backwards while catching a ball
Hii
you are welcome in my ans
Cricketer moves his hand backward while catching a ball to Decrease the rate of change of momentum of ball
According to newton second law of motion "the rate of change of change of momentum of body is directly proportional to the force applied by the body "Since the cricketer move hand backward the time is increased so the rate of change of momentum Decrease so the force Decrease and the injury is minimise .
Matmatical form
Momentum = m*v
rate of change of momentum = m*v/t ( Decrease )
According to newton second law
m*v/t directly proportional Force F
Since mv/t Decrease so Force Decrease so the injury is less .
Answer:
A cricketer moves his hand backwards while catching a ball to prevent his hands from injury.
Explanation:
Due to more time taken to stop the ball, the rate of change of momentum of ball is reduced and hence a small force is exerted on the hands of players. So, the hands of player do not get hurt.
