Asked by Amanda

A railroad car with a mass of 12000 kg collides and couples with a second car of mass 18000 kg that is initially at rest. The first car is moving with a speed of 9 m/s before collision. If external forces can be ignored, what is the final speed of the two railroad cars after they couple?

I don't get why it says couples, what does that mean??? Thanks.
