A cricket bat strikes a ball of mass 0.16 kg travelling towards it. The ball initially hits the bat at a speed of 25 m s⁻¹ and returns along the same path with the same speed. The time of impact is 0.0030 s. You may assume no force is exerted on the bat by the cricketer during the actual collision.
a. Determine the change in momentum of the cricket ball.
b. Determine the force exerted by the bat on the ball.
c. Describe how the laws of conservation of energy and momentum apply to this impact and state whether the impact is elastic or inelastic.
