Physics 1120: Angular Momentum Solutions

The angular momentum of an object moving in a circle is r2mΩ, where r is the radius of rotation. At the centre of the disk r = 0, initially. At the final position, the edge of the disk, r = R. The disk is rotating and thus has an angular momentum by IΩ. Consulting a table of moments of inertia, ...
