A car with mass $1000\,\text{kg}$ is moving downhill on a very steep slope. When the brakes do not work, the driver uses a horizontal sand trap to bring the car to a stop. The car enters the sand at $10\,\text{m s}^{-1}$ and is acted on by a constant force of $2500\,\text{N}$ that slows it down. What distance does the car cover in the sand before it comes to rest?
- A$2.0\,\text{m}$
- B$4.0\,\text{m}$
- C$20\,\text{m}$
- D$40\,\text{m}$
