A 150 g ball, moving horizontally at 20m/s was hit straight back to bowler at 12m/s. If contact with bat lasted for 0.04 sec, then average force exerted by the bat on the ball is:-

A

100N

B

120N

C

150N

D

200N

Text Solution

Verified by Experts

The correct Answer is:
B
`(0.15(20+12))/(0.04)=(12xx32)/(4)=120N`
