A disk (mass of 3 kg, radius 30 cm) is rotating with an angular velocity w1= 5 rad/s. A second disk (mass 2kg, radius 15cm), which is rotating at w= -7 rad/s is dropped on top of the first disk. The disks are dropped so that they share a rotational axis, and they stick together. The moment of inertia of a disk is 1/2mr^2. What is the final angular speed of the two disks?
