The wheel of a motor rotates with a constant acceleration of `4" rad s"^(-1)`. If the wheel starts form rest, how many revolutions will it make in the first 20 second?

Explanation

To solve the problem step by step, we can follow these instructions:

### Step 1: Identify the given values
- **Angular acceleration (α)** = 4 rad/s²
- **Initial angular velocity (ω₀)** = 0 rad/s (since it starts from rest)
- **Time (t)** = 20 seconds

### Step 2: Use the angular displacement formula
