First, review momentum conservation. A car with a mass of 2000 kg is stopped at a red light. Along comes a second car with a mass 1200 kg and an initial speed 40 m/s, and WHAM!!!, it hits the car at rest. How fast did the cars go after the collision, assuming they were stuck together? m,•V + m,•V2= m,•v + m,•V2t
