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

• A. 30 N
• B. 300 N
• C. 150 N

$F=\frac{\Delta p}{\Delta t}=0.15\times \frac{(20-0)}{0.1}$

F = 30 N
