5.A disk of moment of inertia I₁ is rotating about a frictionless shaft with an angular speed wi. It is dropped onto another disk that is initially at rest. Because of friction, the two disks move as one with an angular speed wf. The moment of inertia of the second disk 12 is twice the value of I₁. If w¡ is 12 rpm, what is the final angular speed wf? A. 36 rpm B. 24 rpm C. 6 rpm D. 4 rpm 121 Frictionless shaft At rest
