A new car, car 1, has a spring loaded rear bumper with a force constant of 8.4x105 N/m. While car 1 is parked, a second vehicle, car 2 (with mass of 1.5x103 kg), travels at a constant speed of 18 km/h, hitting car 1 in the rear bumper.

            a)        Calculate the kinetic energy of car 2.

b)        Calculate the distance that car 1’s bumper will compress if car 2 comes to a complete stop after striking it.

A car’s bumper is designed to withstand a 3.0–km/h (0.833–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 0.220 m while bringing a 880–kg car to rest from an initial speed of 0.833 m/s.
