We will first convert
We then use the formula for Angular momentum
Since we are calculating Angular momentum wrt to the center of the circle, and during circular motion
Velocity in a circular motion, given its angular velocity is given by:
Therefore,
Explanation:
The expression for angular momentum is:
We can use the information given to find the velocity
The frequency of rotation
This means that the time period
This means that it takes
We know the circumference of the circle is
This is the distance travelled in
So the velocity is given by:
So we can now get
