An automobile having a mass of 480 kg is driven into a brick wall in a safety test. The bumper behaves like a spring of constant 6.49 × 106 N/m and compresses 4.62 cm as the car is brought to rest. What was the speed of the car before impact, assuming no energy was lost during impact with the wall? Answer in units of m/s
