A person pulls a toboggan for a distance of 40.0 m along the snow with a rope directed 15.0° above the snow. The tension in the rope is 69.0 N.
(a) How much work is done on the toboggan by the tension force?
(b) How much work is done if the same tension is directed parallel to the snow?
(a) 69 * 40 * cos 15 = __ Joules
(b) 69 * 40 = __ Joules
