  A person pulls a toboggan for a distance of 37.4 m along the snow with a rope directed 26.2 ° above the snow. The tension in the rope is 93.8 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?
  
  • The tension in the rope, T = 93.8 N
  The angle of force applied on rope, theeta = 26.2 degrees
  The distance travelled, s = 37.4 m
  
  (a) The workdone by the tension force, W = Fs = Ts = 93.8*37.4 = 3508.12 J
  
  (b) The work done if the same tension is derected parallel to the snow
  W = T s cos(theeta)
  W = 93.8(37.4) cos26.2
  W = 3147.69 J
