PHYS2125 Physics Laboratory I 20225 Kuei Sun The University of Texas at Dallas (3) A disk with moment of inertia 9.15 x 10-3 kg.m initially rotates about its center at angular velocity 5.32 rad/s. A non-rotating ring with moment of inertia 4.86 x 10-3 kg.m right above the disk's center is suddenly dropped onto the disk. Finally, the two objects rotate at the same angular velocity w about the same axis. There is no external torque acting on the system during the collision. Please compute the system's quantities below to 3 sig. figs. 1. Initial angular momentum Li 3. Final angular velocity wy (computed from L;) 2. Initial rotational kinetic energy Ki 4. Final rotational kinetic energy Ky (from wf) 4. Experiment 4.1 Equipment
