A record turntable, that is free to coast without friction, hasa moment of inertiaabout its axis of 6lp, where lo is the moment of inertia of one ofthe records that itplays. Initially the turntable is rotating without friction at 45rev/min with no recordson it. Then two (2) records fall without anvinitial spin onto theturntable. Frictionbetween the records and turntable causes the records to come to thesame finalangular speed as the turntable. What is this angular speed?
