1. The problem statement, all variables and given/known data
Show that the time it takes a wave to propagate up the cable (cable which hangs vertically under its own weight) is t = 2[tex]\sqrt{L/g}[/tex], where L is the cable length.

2. Relevant equations
i think.... v=[tex]\sqrt{F/\mu}[/tex]

3. The attempt at a solution
i've been staring at this problem for about 2 hours now. can anyone just help me how to get started on this one??

Yes. And F is the tension in the cable.
