At which position the kinetic energy of a harmonic oscillator is maximum or minimum ?

Explanation

To determine at which position the kinetic energy of a harmonic oscillator is maximum or minimum, we can follow these steps:

### Step 1: Understand the Motion of a Harmonic Oscillator
A harmonic oscillator undergoes simple harmonic motion (SHM), which can be described by the equation:
\[ y = A \sin(\omega t) \]
where:
- \( y \) is the displacement from the mean position,
- \( A \) is the amplitude,
