Answer:
Explanation:
So suppose the axis of rotation is perpendicular to the surface of the disk, then the moment of inertia can be calculated as the following:
We can convert the rotation speed in term of 0.8 seconds per revolution to the angular velocity knowing that each revolution is 2π
Then the rotational angular momentum of the disk is:
In case the axis of rotation is parallel with the surface, the moment of inertia would have a formula of:
