An automobile having a mass of 1000 kg is driven into a brickwall in a safety test. The bumper behaves like a spring withconstant 5.00e6 M/m and is compressed 3.16cm as the car is broughtto rest. What was the speed of the car before impact, assuming thatno energy is lost in the collision with the wall?
