A 2.8 kg , 20-cm-diameter turntable rotates at 100 rpm on frictionless bearings. Two 500 g blocks fall from above, hit the turntable simultaneously at opposite ends of a diagonal, 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 uniform brass solid cylinder has a mass, m = 500 g, and a diameter, D = 6 cm and a length L = 1 m. The cylinder rotates about its axis of rotational symmetry at an angular velocity of 60 radians/s on a frictionless bearing. (a) What is the angular momentum of the cylinder? (b) How much work was required to increase the angular momentum of the cylinder to this value if the cylinder was initially at rest? Once...

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...

A 210 g toy car is placed on a narrow 70-cm-diameter track with wheel grooves that keep the car going in a circle. The 1.1 kg track is free to turn on a frictionless, vertical axis. The spokes have negligible mass. After the car's switch is turned on, it soon reaches a steady speed of 0.71 m/s relative to the track What then is the track's angular velocity, in rpm? Express your answer to two significant figures and include the...
