The speed of a wheel increases from `600 `rpm to 1200 rpm in `20 s`. What is its angular acceleration ? How many revolutions will it make during this time ?

Explanation

To solve the problem step by step, we will first calculate the angular acceleration and then determine the number of revolutions made by the wheel during the given time.

### Step 1: Convert RPM to Radians per Second

1. The initial angular speed (ω_initial) is given as 600 rpm.
\[ \text{ω_initial} = 600 \, \text{rpm} = 600 \times \frac{2\pi \, \text{radians}}{1 \, \text{revolution}} \times \frac{1 \, \text{minute}}{60 \, \text{seconds}} = 20\pi \, \text{radians/second} \]
