Calculate the Speed of a Wave

  1. Apr 24, 2012 #1
    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

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


    3. 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

    Hello seker,

    Welcome to Physics Forums!

    'Looks right to me so far. :approve:
    :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 ?
