Problem
A cricket ball of mass 0.15 kg is approaching a batsman horizontally at 20 m s⁻¹ and is hit straight back along the same line with the same speed. The time interval of contact between the bat and the ball is 0.040 s.
(i) Calculate the change in linear momentum of the ball.
(ii) Determine the magnitude of the average force exerted by the bat on the ball.
(iii) State the magnitude and direction of the impulse delivered to the ball.
