A railroad car with a mass of 11600 kg collides and couples with a second car of mass 18600 kg that is initially at rest. The first car is moving with a speed of 8.7 m/s prior to the collision. If external forces can be ignored, what is the final velocity of the two railroad cars after they couple?
