Homework Help: Simple Harmonic Wave

  1. Jun 25, 2005 #1
    For a simple harmonic transverse wave that is propagating along a string toward the right, how is maximum speed of a particle on the string calculated?
    Is it

    If A=amplitude and T=Period?

    displacement = s(x,t) = A*sin(ωt - kx + φ)
    particle speed = v(x,t) = ∂s(x,t)/∂t = (ωA)*cos(ωt - kx + φ)
    max particle speed (when cos=1) = ωA = 2πf*A = 2πA/T
