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,

#### Answer:

#### 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
