Homework Statement
A ski gondola is connected to the top of a hill by a steel cable of length L and radius R . As the gondola comes to the end of its run, it bumps into the terminal and sends a wave pulse along the cable. It is observed that it took T seconds for the pulse to return.
What is the tension in the cable?
Homework Equations
v=sqrt(T/mu)
The Attempt at a Solution
With the given information I can calculate velocity and volume of the cable. I can't figure out how to turn that into tension. There's no given mass for calculating mass per unit length, and I can't figure or find any other way of calculating tension.
