The best statement that describes the motion of the cars after the connection is:
**The train cars move together in the direction the large car was moving.**
This is consistent with the principle of conservation of momentum, where the total momentum before the collision is equal to the total momentum after the collision. Since the large train car was moving and collides with the stationary smaller car, both cars will move together in the direction that the large car was originally moving.
