A player caught a cricket ball of mass 150 gm moving ut the rate of 20 m/s if the catchingforce of the blow excreted by the ball on the hands of player is.(a) 0.3 N(b) 30 N(c) 300N(d) 3000N

Answer»

Acceleration = change in velocity/time = (0 - 20) /0.1 = -200m/s²

To calculate force take Acceleration to be positive

Force = mass x Acceleration = 150/1000 x 200 = 30 N
