A person pulls a toboggan for a distance of 34.6 m along the snow with a rope directed 29.3 ° above the snow. The tension in the rope is 110 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?
Fap = 110N @ 29.3o. = Force applied.
Fp = 110*cos29.3 = 95.9 N. = Force parallel to the snow.
a. Work = Fp*d = 95.9 * 34.6 = 3319 J.
b. Work = 110 * 34.6 = 3806 J.
