A car is proceeding at a speed of 12.0 m/s when it collides with a stationary car in front. During the collision, the fist car moves a distance of 0.300 m as it comes to a stop. The driver is wearing her seat belt, so she remains in her seat during the collision. The driver’s mass is 56.0 kg. Neglect any friction between the driver and the seat.

Question

A car is proceeding at a speed of 12.0 m/s when it collides with a stationary car in front. During the collision, the fist car moves a distance of 0.300 m as it comes to a stop. The driver is wearing her seat belt, so she remains in her seat during the collision. The driver’s mass is 56.0 kg. Neglect any friction between the driver and the seat.
