Question:
A car's bumper is designed to withstand a 6.84 km/h (1.9 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 (in N) on a bumper that collapses 0.240 m while bringing a 870 kg car to rest from an initial speed of 1.9 m/s. (Enter a number.)
