A 920 kilogram sports car collides into the rear end of a 2300 kilogram SUV stopped at a red light. The bumpers lock, the brakes are locked, and the two cars skid forward 3.0 meter before stopping. The police officer, knowing that the coefficient of kinetic friction between tires and road is 0.80. Estimate the speed of the sports car at impact. Determine what was that speed?
