Simple harmonic motion object problem

[jaymode]

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.

this is very easy. What equation will you use ?
