A cricketer catches a ball of mass 150 gm in 0.1s and which is moving with a speed of `20 ms^(-1)`, then he experiences force of…………………….

A

300 N

B

30 N

C

3N

D

0.3N

Text Solution

Verified by Experts

The correct Answer is:
B
`"Impulse "="change in momentum"`
`F.Deltat=mv - m u`
`therefore F=(mv-m u)/(Deltat)`
`=(150xx10^(-3)xx20)/(0.1)=30N`
