The angular position of a particle changes from `3` rad to `7` rad in `2` seconds. Calculate the angular velocity of the particle.

Explanation

To solve the problem of calculating the angular velocity of a particle whose angular position changes from 3 rad to 7 rad in 2 seconds, we can follow these steps:

### Step 1: Identify the initial and final angular positions.
- Initial angular position (θ_initial) = 3 rad
- Final angular position (θ_final) = 7 rad

### Step 2: Calculate the angular displacement.
Angular displacement (Δθ) is given by the formula:
