Homework Help: Harmonic Motion

  1. Apr 6, 2007 #1
    I can't figure out what the heck I need to do for this problem.

    3) A body oscillates with simple harmonic motion along the x-axis. Its displacement varies with the time according to the equation A=A sin (wt+ pi/3)

    Where w=pi radians per second, t is in seconds, and a= 7.6m.
    What is the phase of motion at t=2.6s? Answer in units of rad.
