A person pulls a toboggan for a distance of 20.0 m along the snow with a rope directed 25.0° above the snow. The tension in the rope is 85.0 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?
I will be happy to check your work. Break the puling force into horizontal and vertical components.
