Homework Help: physics

Posted by ajo on Sunday, December 9, 2007 at 2:46pm.

A bicyclist rides 5.0km due east, while the resistive force from the air has a magnitude of 3.0N and points due west. The rider then turns around and rides 5.0km due west, back to her starting point. The resistive force from the air on the return trip has a magnitude of 3.0N and points due east. (a) Find the work done by the resistive force during the round trip. (b) Based on your answer to part (a), is the resistive force a conservative force? Explain.

In part a, I got -3.0*10^4J, but I don't understand what it means by a conservative force. Can anyone please explain to me? Thanks a lot!
