Question A car’s bumper is designed to withstand a 6.12-km/h (1.7-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 0.240 m while bringing a 810-kg car to rest from an initial speed of 1.7 m/s.
