A playground merry-go-round of radius 2.1 m has a moment ofinertia159 kg.m2 and is
rotating at 5 rev/min about a frictionless vertical axle. Facingtheaxle, a 34 kg child hops
onto the merry-go-round, and manages to sit down on the edge.
What is the new angular speed of the merry-go-round?

A merry-go-round of radius R=2.0m has a moment of inertia I=250kg m^2, and is rotating at 10rpm. A child whose mass is 25 kg and is at rest grabs onto the edge of the merry-go-round. The new angular speed (in rpm) of the merry-go-round is approximately?

In a playground, there is a small merry-go-round of radius 1.20 mand mass 170 kg. Its radius of gyration is 91.0 cm. A child of mass44.0 kg runs at a speed of 5.00 m/s along a path that is tangent tothe rim of the initially stationary merry-go-round and then jumpson. Neglect friction between the bearings and the shaft of themerry-go-round.
(a) Calculate the rotational inertia of the merry-go-round aboutits axis of rotation.
kg·m2

(b) Calculate the magnitude of the angular momentum of the child,while running, about the axis of rotation of themerry-go-round.
kg·m2/s

(c) Calculate the angular speed of the merry-go-round and childafter the child has jumped on.

A disk-shaped merry-go-round of radius 2.63 m and mass 185 kgrotates freely with an angular speed of 0.631 rev/s. A 56.4 kgperson running tangential to the rim of the merry-go-round at 3.21m/s jumps onto its rim and holds on. Before jumping on themerry-go-round, the person was moving in the same direction as themerry-go-round's rim.

What is the final angular speed of the merry-go-round?
