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 of how many revolutions the wheel makes in the first 20 seconds, we can follow these steps:

### 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 s

### Step 2: Use the angular displacement formula
