A snooker ball with a mass of $200\,\text{g}$ strikes the cushion of a snooker table at right angles, moving at a speed of $14.0\,\text{m s}^{-1}$. It bounces back with one half of its original speed. The ball remains in contact with the cushion for $0.60\,\text{s}$. What is the average force exerted on the ball by the cushion?
- A$2.3\,\text{N}$
- B$7.0\,\text{N}$
- C$2300\,\text{N}$
- D$7000\,\text{N}$
