Coefficient of kinetic friction among tires and road

Reference no: EM13664623

A 900 kg sports car collides into the rear end of a 2100 kg SUV stopped at a red light. The bumpers lock, the brakes are locked, and the two cars skid forward 2.9 m before stopping. The police officer, knowing that the coefficient of kinetic friction among tires and road is 0.75, computes the speed of the sports car at impact. What was that speed?
