An automobile having a mass of 1000 kg is driven into a brick wall in a safety test. The bumper behaves like a spring with constant 4.75  106 N/m and is compressed 2.70 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? m/s

2. When the system is initially at rest, the spring is unstretched and k = 10 lb/ft. Find the velocity of B after it dropped 6 ft. Conservation of energy equation must be used to solve this problem. K- 10 b/ft d=4 5t W = 322 B N |28'8 Ib
