In the winter activity of tubing, riders slide down snow covered slopes while sitting on large inflated rubber tubes. To get to the top of the slope, a rider and his tube, with a total mass of m kg , are pulled at a constant speed by a tow rope that maintains a constant tension of T N . How much thermal energy is created in the slope and the tube during the ascent of a slope that is h meters high, and x meters long
