Aman exerts a constant force to pull a 51-kg box across a floor at 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∘ above the horizontal. the coefficient of kinetic friction for the box-floor interface is μk = 0.12. what is the work done by the man if he moves the box 10m
