ANSWER:
0.0562 J
Explanation:
Angular momentum is expressed in terms of moment of inertia and angular velocity. This is expressed as follows:
Here, I is the angular momentum and ω is the angular velocity.
Angular momentum is mass time the square of the radius of the object. Moment of inertia for a uniform disk is given as,
Here, m is the mass of the disk and r is the radius of the disk.
Replacing:
Convert the units of angular velocity into rad/s.
We replace each data to calculate the angular momentum:
The angular momentum of the uniform disk is 0.0562 J
