Boxes are transported from one location to another in a warehouse by means of a conveyor belt that moves with a constant speed o
f 0.56 m/s. At a certain location the conveyor belt moves for 2.0 m up an incline that makes an angle of 15° with the horizontal. Assume that a 2.1 kg box rides on the belt without slipping. At what rate is the force of the conveyor belt doing work on the box as the box moves up the 15° incline?
