Find Maximum Transverse velocity of string

  1. Nov 17, 2013 #1
    1. The problem statement, all variables and given/known data
    For a string of lenght 100m with fixed ends, a pulse is traveling to the right at a speed of 40 m/sec. The pulse has a wavelength of 2 meters and an amplitude of .1 m.


    2. Relevant equations
    y=A*Sin(kx-wt) ((where w is omega))
    [itex]\lambda[/itex]=2*pi/k
    frequency=w/2pi
    Velocity=w/f
    Velocity=f/[itex]\lambda[/itex]
    V_max=w*A



    3. The attempt at a solution
    So I plugged in as much as I could:
    y=A*Sin(kx-wt)
    [itex]\lambda[/itex]=2 so 2=2pi/k ==> k=pi (?)

    I can't figure out how to get w (omega). So I'm kinda stuck at a dead end. Anyone have any suggestions?

    ω= 2∏/T radians per second
