a 975 N object is pulled at a constant velocity up an incline with a force of 327 n parallel to the incline as shown in the diagram. Assume that the difference between the work output and the work input is the work required to overcome friction. a) what is the force of friction along the incline? the length of the incline is 7 m and the height of the incline is 2.22 m. b) what is the efficiency of the system?
