A 1.5 kg, 20-cm-diameter turntable rotates at 140 rpm on frictionless bearings. Two 500 g blocks fall from above, hit the turntable simultaneously at opposite ends of a diameter, and stick. What is the turntable’s angular velocity, in rpm, just after this event?

A record on a record player spins at 78.3 rpm. Two small 25.0 g balls of clay are dropped on the record and hit it simultaneously, at the edge of the record and at opposite ends from one another. Treat the record as a disk with radius 5.50 cm and mass 530. g, and the clay balls as particles. What is the record's angular velocity just after the clay balls hit it? Give your answer in rad/s.

A 54-cm-long, 500 g bar rotates in a horizontal plane on an axle that passes through the center of the bar. Compressed air is fed in through the axle, passes through a small hole down the length of the bar, and escapes as air jets from holes at the ends of the bar. The jets are perpendicular to the bar's axis. Starting from rest, the bar spins up to an angular velocity of 200 rpm at the end of 12...
