How much work is done if the same tension is directed, Ask an Expert

Academics

Q. A person pulls a tobaggan for a distance of 35.0m along the snow with a rope directed 25.0 degrees above the snow. The tesion in the rope is 94.0N (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?

Q. A mobile at the art museum has a 2.0 steel cat and a 4.0 steel dog suspended from a lightweight cable. It is found that angle 1 = 21 degrees when the center rope is adjusted to be perfectly horizontal.

What is the tension in the rope 3? What is the angle of rope 3?
