A 50.0-kg child stands at the rim of a merry-go-round of radius 2.00 m, rotating with an angular speed of 3.00 rad/s. What minimum coefficient of static friction is required? Is the answer you found reasonable? In other words, is she likely to stay on the merry-go-round?

A playground merry-go-round of radius 2.00 m has a moment ofinertia I = 275 kg·m2 and is rotating about a frictionless verticalaxle. As a child of mass 25.0 kg stands at a distance of 1.00 mfrom the axle, the system (merry-go-round and child) rotates at therate of 14.0 rev/min. The child then proceeds to walk toward theedge of the merry-go-round. What is the angular speed of the systemwhen the child reaches the edge?
1 rad/s
