Annnnnddd the Grand Finale

PHYSICS FINAL!!! 8:00 AM MONDAY!!! WOOO!!!

Needless to say... I need some luck and a hell of a lot study time. So if you will excuse me, there is an inclined plane at an angle theta on Mars with a coefficient of friction mu and a box of mass m is sliding down. At the end of the plane, there is a spring with the spring constant of k. How far will the box slide back up the plane after bouncing of the spring? 

I made all that up. I'm going to kill myself now...
