What is the angular momentum of the disk about the axle?

L = 0.5*M*R^2 * w

Explanation:

Solution:-

- The angular Momentum (L) of a rigid body about any axis is given by the following relationship:

L = I*w

Where,

I : Moment of inertia of the rigid body

w: The angular speed of the rigid body.

- The moment of inertia (I) for a disc is given by:

I = I_disc

I = 0.5*M*R^2

Where,

M : Mass of the disc

R : The radius of the disc.

- Hence, the Angular momentum (L) of the disc rotating about an axle is:

L = 0.5*M*R^2 * w
