Question

Ex5. A batsman in the net hits a ball of mass 0.15 kg at a speed of 40 m/s. The ball strikes the netting and is brought to rest in 0.5 s. Find the average force exerted by the netting on the ball.

Answer 1

F = 12N
As the ball is having initial velocity = 40m/s
it will deaccelerate to come to rest.
therefore,
using, v=u+at
a = - 40/0.5
= 80 metre per second square
Now,
F = ma
= 0.15× 80
= 12 N
