How Do You Calculate Maximum Acceleration of a Simple Harmonic Oscillator?

[Bearbull24.5]

Homework Statement

A simple harmonic oscillator has amplitude 0.49 m and period 3.7 sec.
What is the maximum acceleration?

Homework Equations

a(max)=Aw^2
w=angular frequency
Vmax=Aw
w= angular frequency

The Attempt at a Solution

I attempted to divide the Amplitude (.49m) by the time (3.7 sec) in order to find the maximum velocity. Plugging this value (.132432m/s) into the maximum velocity equation (Vmax=Aw) to solve for w I got a value of .27027027 which I plugged into the maximum acceleration equation to get a value of .035792549. Which was wrong

w =2π/T
T:period.
i think you can find w with this equation.

That worked, thank you very much
