WAVES and vibrations

  1. Mar 22, 2009 #1
    1. The problem statement, all variables and given/known data
    Tension is maintained in a string as in the
    figure. The observed wave speed is 26 m/s
    when the suspended mass is 3.2 kg .What is the mass per unit length of
    the string? The acceleration of gravity is
    9.8 m/s2 . Answer in units of kg/m

    3. The attempt at a solution
    can someone please guide me in the direcxtion of which i should aproach the problem because im really confused

    There is an equation for wave speed on a string. It has to do with tension and mass-per-length, and should be in your text book.

    do u mean v=frequency(wave length)

    No, not that one. It should involve the string's tension, as well as the mass-per-unit-length.
