a cricket ball of mass 150g is moving with a velocity of 12m/s and hitted by a bat so that the ball is turned back with a velocity of 20m/s. if the duration of contact btw the ball and bat is 0.01s.then:
1. Find the average force exerted by the bat on the ball

F=m(v-u)/t
=150(8)×10^-3/10^-2
=120N
=150(8)×10^-3/10^-2
=120N

we know that
F=ma
F=m(v-u) /t
now putting the value
m=150x10^-3
v=20m/s
u=12m/s
t=0.01s
you will give the answer is 90N
