A man exerts a constant force to pull a 55-kg box across a floor at a constant speed. He exerts this force by attaching a rope to the box and pulling so that the rope makes a constant angle of 36.9 degrees above the horizontal. The coefficient of kinetic friction for the box-floor interface is 0.25. What is the work done by the man if he moves the box 10m
