For a simple harmonic oscillator, the maximum acceleration is amaxa_{\text{max}}amax when the amplitude is AAA. The frequency of the oscillations is fff.
Which expression is correct for this oscillator?
amax=2πf2Aa_{\text{max}} = 2\pi f^2 Aamax=2πf2A
amax=4π2fAa_{\text{max}} = 4\pi^2 f Aamax=4π2fA
amax=4π2f2Aa_{\text{max}} = 4\pi^2 f^2 Aamax=4π2f2A
amax=2πfAa_{\text{max}} = 2\pi f Aamax=2πfA
