A player takes 0.1 s in catching a ball of mass 150 g moving with velocity of 20m/s. the force imparted by the ball on the hands of the player is

A

3N

B

0.3N

C

30N

D

300N

Text Solution

Verified by Experts

The correct Answer is:
C
Force = Rate of change of momentum
`=(m(v-u))/(t)= (150xx10^(-3)xx(0-20))/(10^(-1))`
`= -20xx150xx10^(-2)= -30N`
This is the force exerted by the hand on the ball.
`therefore` The ball exerts a force of 30 N on the hands of the player.
