A vertical solid disk of uniform mass $M=9kg$ and radius $R=0,61m$ is pivoted from point $O$ as shown in the figure below. A constant radial force of $F=119N$ is applied where the angle $=42,$ if $=0,22m,$ determine the angular acceleration of the disk in si units at the instant shown. Express your answer using two decimal places. Please use the codvention: Clockwise $(-).$ Counterclockwise $(+)$ when expressing your answer.

Hint $1$: The moment of inertia of a uniform disk about an axis of rotation passing through the center of mass $($CM$)$ is $I_{CM}=M\frac{R2}{2}.$

Hint $2$: Don't forget the force of gravity. Take $g=9\mathrm{.}80\frac{m}{s2}.$
