A person pulls a toboggan for a distance of 40.0 m along the snow with a rope directed 20.0° above the snow. The tension in the rope is 67.0 N.
(a) How much work is done on the toboggan by the tension
force?
_________J
(b) How much work is done if the same tension is directed parallel
to the snow?
_________J
Homework Answers
workdone by tension
Wt = T d cos x
Wt = 67* 40 * cos 20
Wt = 2518.376 J
=======
Wt' = 67 * 40 = 2680 J
======
Comment in case any doubt, will reply for sure.. Goodluck
