This would provide a difference in time of movement as well as distance differences. If students have trouble with the questions, the equipment should still be available. Describe the motion of the passenger during and after the front-end collision. Describe the motion of an unbelted passenger in a car which collides with a stationary obstacle. Draw a diagram of the forces acting on the cart and on the passenger on the flat before and during collision.
Seatbelts prevent a passenger from being thrown from the car.
Explain how this applies to the motion of the passenger during the collision. My observation tends to the idea that mature individuals use seatbelts more than teenagers do. However, European countries do not have speed limits on their highways.
