A disk of mass M is spinning freely at 4.49 rad/s when a second identical disk, initially not spinning, is dropped onto it so that their axes coincide. In a short time the two disks are corotating. a) What is the angular speed of the new system (in rad/s)? b) If a third such disk is dropped on the first two, find the final angular speed of the system (in rad/s).

Bar OA has a counterclockwise angular velocity ω0 = 3.4 rad/s. Rod BC slides freely through the pivoted collar attached to OA. Determine the angular velocity ωBC of rod BC (positive if counterclockwise, negative if clockwise) and the velocity Vrel of collar A relative to rod BC (positive if moving from B to C, negative if it moves from C towards B).
