Question:
In the railroad freight yard, an empty freight car of mass m rolls along a straight level track at 1.50 m/s and collides with an initially stationary, fully loaded boxcar of mass 6.30m. The two cars couple together on collision.
Suppose instead that the two cars are at rest after the collision. With what speed was the loaded boxcar moving before the collision if the empty one was moving at 1.50 m/s?
