Question1

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 5.95 106 N/m and is condensed 3.53 cm as the car is brought to rest. What was the speed of the car before impact; assume no energy is lost in the collision with the wall?

Question2
