William Grainger's answer to What is the angular velocity of each masses? - Quora

So the claim is that two discs, one spinning dropped on another of the same mass and size will result in a final angular velocity of half, and I say it will result in a final angular velocity of 0.707times. Why is no data is forthcoming. Am I right?
