A tennis ball with mass $55\,\text{g}$ moves horizontally at a speed of $30\,\text{m s}^{-1}$. It then strikes a wall and rebounds horizontally with a speed of $20\,\text{m s}^{-1}$. The ball remains in contact with the wall for $5.0 \times 10^{-3}\,\text{s}$. What is the average force exerted on the wall by the ball?
- A$110\,\text{N}$
- B$220\,\text{N}$
- C$330\,\text{N}$
- D$550\,\text{N}$
