A car's bumper is designed to withstand a 4.68-km/h (1.3-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 0.210 m while bringing a 870-kg car to rest from an initial speed of 1.3 m/s. 2692.86 3 N
