A sledge loaded with bricks has a total mass of 18 kg and is neing pulled by a constant speed by a rope inclined at 20° above the horizontal. The sledge moves a distance of 20 m and = 0.5. The force pulled on the rope is 79.4 N. a) How much work is being done by the rope? b) Find the work done by friction?
