Boxes are transported from one location to another in a warehouse by means of a conveyor belt that moves with a constant speed of 0.60 m/s. At a certain location the conveyor belt moves for 5.0 m up an incline that makes an angle of 13 with the horizontal, then for 5.0 m horizontally, and finally for 5.0 m down an incline that makes an angle of 13 with the horizontal. Assume that a 2.0 kg box rides on the belt without slipping. At what rate is the force of the conveyor belt doing work on the box (a) as the box moves up the 13 incline, (b) as the box moves horizontally, and (c) as the box moves down the 13 incline?
