Homework Help: Physics

Posted by Kyle on Tuesday, October 30, 2012 at 1:53am.

"A slinky that satisfies v = sqrt(T/_mu) is stretched 12m. The mass of the slinky is 0.8kg. The tension on the slinky is 4N. What is the expected wave speed?"

To get mu, I divided the mass by the length then plugged that into the equal and solved for v but I'm not getting the correct answer.
