A player caught a cricket ball of mass 150g moving at a rate of `20m//s`. If the catching process is completed in 0.1s, the force of the blow exerted by the ball on the hand of the player is equal to

Options

A. 3 N
B. 30 N
C. 300 N
D. 150N

Answer

B

Explanation

As impulse = change in momentum
` therefore F xx t = m (u - v)`
` or F xx 0.1 = (150) /( 1000) ( 20 -0) or F= 30 N`
