When are the velocity and acceleration in the same direction SHM?

Explanation

To determine when the velocity and acceleration are in the same direction in Simple Harmonic Motion (SHM), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Equation of SHM**:
The position of a particle in SHM can be described by the equation:
\[
x(t) = a \sin(\omega t)
