19. A record turntable has a moment of inertia about its rotation axis of Io- Initially it is at rest. Three spinning records then fall onto it and stick to it. Each record has a moment of inertia I1, where I1 = (1/4) lo, and an initial angular speed of wo. What is the angular speed that the turntable and three records have after they stick together? (o spurring (initially) at rest (initially) A (2/3) @0 B (4/3) (0 C (3/5) wo D (3/7) (0 E (5/7) wo
