A playground merry-go-round of radius R = 1.80 m has a moment of inertia I = 230 kg⋅m2 and is rotating at 12.0 rev/min about a frictionless vertical axle. Facing the axle, a 23.0−kg child hops onto the merry-go-round and manages to sit down or edge. What is the new angular speed of the merry-go-round? rev/min

is no friction between block A and the tabletop. The mass of block B is 4.90 kg. The pulley rotates about a frictionless axle, and the light rope doesn't slip on the pulley surface. The pulley has radius 0.200 m and moment of inertia 1.30 kg⋅m2. Part A If the pulley is rotating with an angular speed of 8.00 rad/s after the block has descended 1.20 m, what is the mass of block A ? Express your answer with the appropriate units.

A playground carousel is rotating counterclockwise about its center on frictionless bearings. A person standing still on the ground grabs onto one of the bars on the carousel very close to its outer edge and climbs aboard. Thus, this person begins with an angular speed of zero and ends up with a nonzero angular speed, which means that he underwent a counterclockwise angular acceleration. The carousel has a radius of 1.52 m, an initial angular speed of 3.23 rad/s, and a moment of inertia of 128 kg⋅m2. The mass of the person is 41.5 kg. Find the final angular speed of the carousel after the person climbs aboard. ωf =

A uniform spherical shell of mass M = 18.0 kg and radius R = 0.990 m can rotate about a vertical axis on frictionless bearings (see the figure). A massless cord passes around the equator of the shell, over a pulley of rotational inertia I = 0.100 kg⋅m2 and radius r = 0.120 m, and is attached to a small object of mass m = 3.30 kg. There is no friction on the pulley's axle; the cord does not slip on the pulley. What is the speed of the object when it has fallen a distance 0.820 m after being released from rest? Use energy considerations.
