Homework Statement



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?


Homework Equations



[tex]v=\sqrt\frac{F}{m/L}[/tex]


The Attempt at a Solution



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

[tex]v=\sqrt{35/0.075}[/tex]

v= 25 m/s

'Looks right to me so far. :approve:
v= 25 m/s
: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 ?
