A 245-Kg Child Is Standing on the Outer Edge of a a Horizontal

Short Answer

A 24.5-kg child is standing on the outer edge of a horizontal merry-go-round that has a
moment of inertia of $$989 \mathrm {~kg} \cdot \mathrm { m } ^ { 2 }$$ about a vertical axis through its center and a radius of
2.40 m. The entire system (including the child) is initially rotating at 0.180 rev/s. Find the
angular velocity if the child moves to a new position 1.10 m from the center of the
merry-go-round.
