Acar's bumper is designed to withstand a 4.32 km/h (1.2-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 0.195 m while bringing a 910 kg car to rest from an initial speed of 1.2 m/s.
