Homework Help: physics

Posted by Mark on Monday, November 1, 2010 at 12:35pm.

Suppose I have a circular metal disk spinning at a constant angular velocity. Now imagine near to, but not in contact with the first disk, I have an identical metal disk spinning at the same angular velocity but in the opposite direction (ie. W1 = -w2) and the surfaces are parallel to one another. What is the total angular momentum? (ignore friction)
