Simple Harmonic Motion: Acceleration Max/Min

Click For Summary
SUMMARY

In simple harmonic motion (SHM), acceleration reaches its maximum at the extreme positions of the motion, where the displacement is greatest. Conversely, acceleration is at its minimum when the object is at the equilibrium position, where speed is maximized. This relationship is governed by Newton's 2nd law, which links force, mass, and acceleration. The phase difference between the sinusoidal function of displacement and its derivative indicates the points of maximum and minimum acceleration.

Hi, i need some help for a physics question: when is acceleration at maximum and when is acceleration at minimum in a simple harmonic motion. i know when the speed is at maximum: at the equilibrium position; however, i do not know about the acceleration. Please note that direction does not matter

Hint: Consider Newton's 2nd law.
 
You know where the speed is maximized.

The difference in phase between a sinusoidal function and it's derivative is the difference between the maximized speed and the maximized acceleration.
