A cricket ball of mass 150 kg is moving ...

A cricket ball of mass 150 kg is moving with a velocity of `12 m//s` and is hit by a bat so that ball is turned back with a velocity of `20 m//s` . The force of the blow acts for 0.01 s on the ball . Find the average force exerted by the bat on the ball.

A

the change in momentum of the ball is 48 kg-m/s.

B

the average force exerted by the bat on the ball is 480 N.

C

the change in momentum of the ball is 1.2 kg-m/s

D

the average force exerted by the bat on the ball is 120 N.
