59. Their angular velocities, when they are stuck to each other, are equal, regardless of whether they share the same central axis. The initial rotational inertia of the system is IIIIMR0212=+=bigdisksmalldiskbigdiskwhereusing Table 10-2(c). Similarly, since the small disk is initially concentric with the big one, Imrsmalldisk=122. After it slides, the rotational inertia of the small disk is found from the parallel axis theorem (using h= R– r). Thus, the new rotational inertia of the system is ()22211.IMRmrm R r+−(a) Angular momentum conservation,
