A disk of radius R and mass M is spinning at an angular velocity ω0 rad/s. A non-rotating concentric disk of mass m and radius r drops on it from a negligible height and the two rotate together. If R is 1.5 of r and M is 1.2 of m, what is the final angular velocity in terms of ω0? The moment of inertia of a solid cylinder is (1/2)MR2. (First got 0.64ω0, the second time I got 0.56 ω0)
