13. A car's bumper is designed to withstand a 4.0-km/h (1.12-m/s) collision with an immovable object without damage to the body of the car. The bumper cushions the shock by absorbing the force over a distance. Calculate the magnitude of the average force on a bumper that collapses 0.200 m while bringing a 900-kg car to rest from an initial speed of 1.12 m/s.

Transcribed Image Text:**Problem 13: Bumper Force Calculation**
A car's bumper is designed to withstand a 4.0 km/h (1.12 m/s) collision with an immovable object without damage to the body of the car. The bumper cushions the shock by absorbing the force over a distance. Calculate the magnitude of the average force on a bumper that collapses 0.200 m while bringing a 900-kg car to rest from an initial speed of 1.12 m/s.
**Explanation:**
- **Context:** This problem involves the physics concept of mechanics, specifically the calculation of force during a collision.
- **Objective:** To calculate the average force exerted on the bumper.
- **Given Data:**
- Initial speed of the car: 1.12 m/s
- Final speed of the car: 0 m/s (since it comes to rest)
- Mass of the car: 900 kg
- Distance over which the bumper collapses: 0.200 m
