Question

A child of mass 54.7 kg sits on the edge of a merry-go-round with radius 2.3 m and moment of inertia 222.81 kgm2. The merrygo-round rotates with an angular velocity of 1.6 rad/s. What radial force does the child have to exert to stay on the merry-go-round? Answer in units of N.
Not sure what this question is about. Friction is holding the kid on. As long as mu mg is greater than mr omega^2 the kid stays on. I guess just answer m r omega^2. Moment has no bearing in this case.
