What is the average force between a cricket bat and ball during collision? For this rough calculation, let's assume that the ball's initial and final velocities with respect to the bat are anti-parallel and have magnitudes of about 100 kph. Suppose the collision lasts about 1 m/s. A cricket ball has a mass of }0.16 kg. The average force between bat and ball is _____ N. Do not use exponent notation. (I'm using conservative values here: bowlers (the people who deliver the ball to batsmen) bowl at over 150 \text{ kph}150 kph and, even though air resistance slows the ball down considerably by the time it reaches the batsman, the bat is often travelling rapidly in the other direction. So both velocities used here are probably exceeded substantially in professional games. I'm guessing that, because the cricket ball is hard, the collision might last less about 1 m/s.
