The ml$-$g bullet having a velocity of $800\frac{m}{s}$ is fired into the edge of the $m2*kg$ disk as shown. Determine the angular velocity of the disk just after the bullet becomes embedded into its edge. Also, calculate the angle $$ the disk will swing when it stops. The disk is originally at rest. The rodAB has a mass of $3kg.$

$m1=10+a$

$m2=5+b$
