A thin rod of length L and mass M rotates at angular speed w anti-clockwise. A downwards particle of mass
* and speed vo hits the rod at distance d from the rod's axis and perpendicular to the rod. The particle
then sticks onto the rod at its impact point.
(a) At what value of d are the rod and particle stationary after the hit?
(b) If d is greater than the value found in (a), in which direction do the rod and particle rotate?
Two solid disks with masses m, = 3m and m,= 2m are rotating freely without friction with angular velocities w,=w and w,= 2w, respectively about the same
vertical axel passing through their centers of mass as shown (R,=2R and Ry- R). As indicated w, and w,are in opposite directions. The upper disk is dropped
down the axle to land on and couple with the lower disk (due to friction). The disks rub against each other and finally reach a common final angular velocity wr
