If the coefficient of kinetic friction between crate and floor is 0.30, how much work is done by the person? (Assume the rope is attached to the center of mass of the crate)

Draw a picture and label as much as you can as possible. Write/type out some equations that involve some of the stuff involved, and see if you can't make a guess at how to use them to get what you want. I'll be here to help you out, so don't worry about messing up, cause if you do, I can help fix exactly where you need it.
