Homework Help: physics

A string connecting a car of mass x1 on an air track is connected to another mass, x2, by a string over a pulley. If the string has appreciable mass will the car still undergo constant acceleration? Explain

I think that the car will still undergo constant acceleration, the acceleration would just be different than if the string had no appreciable mass. I'm not sure about my answer though, so if someone could explain why I'm right or wrong, I would greatly appreciate it.
