A wheel makes 20 revolutions per minute. Find the angular velocity.
Question
A wheel makes 20 revolutions per minute. Find the angular velocity.
Solution
To find the angular velocity, we need to know the formula for angular velocity. The formula for angular velocity is:
Angular velocity = (2π * Number of revolutions) / Time
In this case, the number of revolutions is given as 20 per minute. So, we can substitute this value into the formula:
Angular velocity = (2π * 20) / 1
Simplifying the equation, we get:
Angular velocity = 40π
Therefore, the angular velocity of the wheel is 40π.
