Twо freight cаrs аre mоving оn а frictionless, horizontal track. A 5,000-kg freight car moving at an unknown velocity collides with a 10,000-kg freight car that is initially at rest. The cars couple together after the collision and move as one object at 2 m/s. Calculate the initial speed (vAi) of the 5000-kg freight car?
