A uniform solid disk of mass $m=3\mathrm{.}08kg$ and radius $r=0\mathrm{.}200m$ rotates about a fixed axis perpendicular to its face with angular frequency $5\mathrm{.}95$ rad $\frac{?}{s}.$

$($a$)$ Calculate the magnitude of the angular momentum of the disk when the axis of rotation passes through its center of mass.

$kg*\frac{m^2}{s}$

$($b$)$ What is the magnitude of the angular momentum when the axis of rotation passes through a point midway between the center and the rim?

$kg*\frac{m^2}{s}$
