Physics Problem

What is the work done by tension on a rope with a rock attached to its end if you swing the rope in a circular trajectory?

Isn't it just zero?

should be 0...work = force*distance right?

That's what I thought.

I'm way too old to be thinkin' about that shit now...what is the work done by my poop as it circles the bowl during a flush...that's more relevant. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

The rope doesn't do work. There is force imparted on it, and work is done to it.

They are probably wanting to know how much work is done on the rope or how much work is done on the rock transmitted through the rope.

What is the work done per one revolution by tension in a suspended 2-

m rope with a 150 g tennis ball attached to its end if you swing the rope

2 times a second such that the tennis ball is in a circular trajectory?

There is the exact problem.

I bet Anton knows the answer.

He probly has it tattooed on his massive 15" ****.

work is 0. the rope would be at the same place the start.
