Problem

A cricket ball of mass

0.15\,\text{kg}

approaches a batsman at

20\,\text{m s}^{-1}

and is hit back along the same line with the same speed. If the duration of contact between bat and ball is

0.01\,\text{s}

, what is the magnitude of the average force exerted by the bat on the ball? a)

450\,\text{N}

600\,\text{N}

300\,\text{N}

900\,\text{N}
