WOULD THIS BE A GENERAL PLANE MOTION EXAMPLE OR JUST TRANSLATION

PROBLEM $15\mathrm{.}30$

The system shown is held at rest by the brake$-$and$-$drum system shown. After the brake is partially released at $t=0,$ it is observed that the cylinder moves $5$ m in $4\mathrm{.}5$ s $.$ Assuming uniformly accelerated motion, determine $($a$)$ the angular acceleration of the drum, $($b$)$ the angular velocity of THE DRUM
