Q. A 50 kg child stands at the rim of a merry-go-round of radius 2 m, rotating with an angular speed of 3 rad/s. (1) what is the child's centripetal acceleration? (2) What is the minimum force between his feet and the floor of the carousel that is necessary to keep him in the circular path? (3) What minimum coefficient of static friction is required? Is the reply you found reasonable? In other words, is he probable to stay on the merry-go-round?
