Question

A cricket ball of mass 120g is moving with a velocity of 12m/s and is hit by a bat so that the ball is turned back with a velocity of 20m/s. If duration of contact between ball and bat is 0.001s.Find the impulse and the average force exerted on the ball by the bat

Answer 1

Answer:

Impulse=F×t= Change in Momentum

⇒ Change in Momentum =mv−mu=0.15(12)−0.15(−20)=4.8

⇒F×0.001=4.8  

⇒F=4800N  

Therefore, A is correct option.
