Evaluate the new angular speed of the merry-go-round

Reference no: EM13537020

A playground merry-go-round of radius 1.9 m has a moment of inertia 272 kg.m2 and is rotating at 6 rev/min about a frictionless vertical axle. Facing the axle, a 23 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?
