A Disk With Moment Of Inertia Is Rotating With Initial Angular Speed Wo A Second Disk With Moment Of Inertia 2 Init 1 (71.74 KiB) Viewed 7 times

A disk with moment of inertia /₁ is rotating with initial angular speed wo; a second disk with moment of inertia /2 initially is not rotating (see Figure P.66). The anatigementis much like a LP record ready to drop onto an unpowered, freely spinning turntable. The second disk drops onto the first and friction between them brings them to a common angular speed w. Show that (0) = 1₁ + 1₂ FIGURE P.66 4₂ Direction of spin
