Question

A cricket ball of mass 145 g is moving with a velocity of 14 m/s and is being hit by a bat ,so that the ball is turned back with a velocity 22m/s .the force of below acts on the ball for o.o15s .find out the average force exerted by bat on ball

Answer 1

acceleration =(22-(-14))/0.015 becoz direction had changed
@=36/0.015=2400m/second square
f=m×a=0.145×2400

Answer 2

Answer:

Explanation:

To find :

F = ?

Solution :

As,

➸ F x t = Impulse = change in momentum

➸ F x 0.01

➸ m (v - u)

➸ 0.150 (- 20 - 12)

➸ F = -0.15 x 32/0.01

....

➸ F = - 480N
