An automobile having a mass of 1,000 kg is driven into a brick wall in a safety test. The bumper behaves like a spring with constant 5.85 106 N/m and is compressed 2.88 cm as the car is brought to rest. What was the speed of the car before impact, assuming no energy is lost in the collision with the wall?
