At what position of a body executing shm its velocity (i) maximum and (ii) zero ?

Explanation

To determine the positions of a body executing Simple Harmonic Motion (SHM) where its velocity is maximum and zero, we can follow these steps:

### Step 1: Understand the equation of SHM
The equation for a body in SHM can be expressed as:
\[ y(t) = A \sin(\omega t) \]
where:
- \( A \) is the amplitude,
- \( \omega \) is the angular frequency.
