A sоlid disk is mоunted sо it cаn rotаte without friction аbout an axis through its center. Initially, it rotates with some angular velocity ω0{"version":"1.1","math":"ω0"}. A second disk, initially not rotating, is dropped concentrically onto the disk. The second disk has the same mass and half the radius of the first disk. When the two come to a common rotation, what is the final angular velocity?
