Homework Help: Simple harmonic motion object problem

  1. Apr 8, 2005 #1
    I have this problem:
    An object is undergoing simple harmonic motion with period 0.330 s and amplitude 5.95 cm. At t=0 the object is instantaneously at rest at x= 5.95 cm.

    i need to find :
    the time it takes the object to go from x= 5.95 cm to x= −1.49 cm.

    I have tried using x = A cos(wt + phase angle)

    but get stuck.
