In a parking lot, an SUV of mass 2000 kg driving at 5 m/s collides head on with a sports car of mass 1000 kg driving in the opposite direction. The bumpers lock and the cars skid with locked brakes on the wet pavement (kinetic friction coefficient 0.1) for 2 m before they come to rest. We are interested in the velocity of the sports car before the collision.
(A) The problem naturally breaks into two parts.What are the parts?
(B) Which conservation laws apply?
(C) Determine the velocity of the sports car before the collision. Please use g = 10 m/s2and make sure your units work out.
