Question: A DVD (radius 6.0 cm) is spinning freely with an angular velocity of 1200 rpm when a bug drops onto and sticks to the DVD

A DVD (radius 6.0 cm) is spinning freely with an angular velocity of 1200 rpm when a bug drops onto and sticks to the DVD a distance 4.5 cm from the center. If the DVD slows to 800 rpm, what is the ratio of the bug’s mass to the DVD’s mass? (Ignore the effect of the hole in the center of the DVD.)
