A snooker ball has a mass of 200 g. It hits the cushion of a snooker table and rebounds along its original path. The ball arrives at the cushion with a speed of $14.0\,\mathrm{m\,s^{-1}}$ and then leaves it with a speed of $7.0\,\mathrm{m\,s^{-1}}$. The ball and the cushion are in contact for a time of 0.60 s. What is the average force exerted on the ball by the cushion?

1. A1.4 N
2. B2.3 N
3. C4.2 N
4. D7.0 N
