Boxes are transported from one location to another in a warehouseby means of a conveyor belt that moves with a constant speed of0.52 m/s. At a certain location the conveyor belt moves for 2.0 mup an incline that makes an angle of 20° with the horizontal.Assume that a 2.1 kg box rides on the belt without slipping.
(a) At what rate is the force of the conveyor belt doing work onthe box as the box moves up the 20° incline?
