In the winter activity of tubing, riders slide down snowcovered 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 \(80 \mathrm{~kg}\), are pulled at a constant speed by a tow rope that maintains a constant tension of \(340 \mathrm{~N}\). How much thermal energy is created in the slope and the tube during the ascent of a 30-m-high, 120 -m-long slope?
