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

Answer

A

Explanation

We define average force as : `|vec(F_("average"))| = |(Delta vec(p))/(Delta t)| = (P_("final" ) - P_("initial"))/("duration") = |((0 - 0.150 xx 20))/(0.1)| = 30 N`
