A wall is struck by a strong wind travelling at $33\,\text{m s}^{-1}$. The air density is $1.2\,\text{kg m}^{-3}$. The wall presents an area of $12\,\text{m}^2$ perpendicular to the wind velocity. When the air reaches the wall, its speed is reduced to zero. What is the approximate force exerted by the air on the wall?
- A$330\,\text{N}$
- B$400\,\text{N}$
- C$480\,\text{N}$
- D$16000\,\text{N}$
