Figure 6
. An automobile having a mass of 1000 kg is driven into a brick wall in a safety test.
The bumper behaves like a spring of force constant 5.00 , 106 N/m and compresses
3.16 cm as the car is brought to rest. What was the speed of the car before impact,
assuming that no mechanical energy is lost during impact with the wall?
