A person pulls a toboggan for a distance of 30.0 m along the snow with a rope directed 15.0° above the snow. The tension in the rope is 99.0 N.
(a) How much work is done on the toboggan by the tension force?

(b) How much work is done in the same tension is directed parallel to the snow?

  • Physics -

    work= tension*distance*cos15

    if the angle is zero, use the above formula, new angle.
