A string connecting a car of a certain 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 it will still undergo a constant acceleration, but the acceleration will just be different than if the string had no appreciable mass. I'm not sure if I'm right, so if anyone can tell me if I'm right or wrong, I would greatly appreciate it.
