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 70 kg, are pulled at a constant speed by a tow rope that maintains a constant tension of 350 N.
Required:
How much thermal energy is created in the slope and the tube during the ascent of a 30-m-high, 120-m-long slope?
