A ball is moving with a momentum of $25\text{ kg m s}^{-1}$ and strikes a wall head-on. It bounces back from the wall at the same speed, but in the opposite direction. The collision lasts for $50\text{ ms}$. What is the average force exerted on the wall by the ball during the collision?
- A$0.50\text{ N}$
- B$1.00\text{ N}$
- C$500\text{ N}$
- D$1000\text{ N}$
