Question

A car is moving at high speed along a flat highway when the driver brakes hard. The wheels become locked (stop rolling), and the tires slide along the roadway. The resulting skid marks are 32.0 meters long. If the coefficient of kinetic friction between tires and road is 0.550, and the deceleration was constant during braking, how fast was the car going when the wheels became locked? (You must use a free body diagram to work out the acceleration due to friction.
