Question

A 150 g ball travelling at 30 m/s strikes the palm of a player's hand and is stopped in 0.06 seconds. Calculate the force exerted by the ball on the hand.


(d) - 75 N


(a) 75 N


(c) - 750 N


(b) 750 N

Answer 1

Answer:Given:

m=150g=0.15kg

u=30m/s

v=0m/s

t=0.05sec

F=mxa

=0.15 * (v-u)/t

=0.15*(0-30)/0.05

=3 x -30

=-90N

hope it helps u
