13. A ring is dropped on a rotating cylindrical table. The ring is centered on the table and oriented with the same axis as the table. The ring has a moment of inertia of 2.0 kg.m2 and the table has moment of inertia of 4.0 kg.m2. The ring is initially not rotating and the table is rotating 5.0 rad/s. What is the angular momentum of the two after the drop? answer is 20
