Answer to Question #74312 in Physics for Olivia

Question

A car’s bumper is designed to withstand a 4 km/h collision with an immovable object without damaging the body of the car. The bumper cushions the shock by absorbing the force over a distance. Calculate the magnitude of the average force in a bumper that collapses 0.205 m while bringing a 875 kg car to rest from an initial speed of 1.2 m/s, in Newtons.
