1. The problem statement, all variables and given/known data

A vibrating rope has a linear density of 0.075 kg/m. If a tension of 35 N is applied to the rope what will be the speed of a wave travelling along the rope?

2. Relevant equations

$$v=\sqrt\frac{F}{m/L}$$

3. The attempt at a solution

Just wanted to see if I am headed in the right direction.

$$v=\sqrt{35/0.075}$$

v= 25 m/s

Hello seker,

Welcome to Physics Forums!

'Looks right to me so far.
:uhh: Try calculating that again.

Thanks! Have not done Physics in so long and now have a bunch I need to do.

V= 21.6 ?

That looks better.
