What is the wave speed?

  1. Jul 1, 2009 #1
    The linear density of a string is 5.520×10-3 kg/m. A transverse wave on the string is described by the equation

    y=(0.033 m)sin(2.50 m-1x +125.7 s-1 * t).

    1.) What is the wave speed?




    2.) What is the tension in the string???


    I've already calculated the wave speed but I don't know how to do the tension in string!

    HELP PLS!

    wave speed (v) = w/k

    y= Asin(kx-wt)

    w = 125.7
    k=2.5

    v = 125.7/2.5 = 50.38 m/s (wave speed)


    But i do not know how to calculate the tension!!! HELP PLEASEE!!
