What is the angular velocity of the merry-go-round

Reference no: EM13314194

A child of mass 51 kg sits on the edge of a merry-go-round with radius 1.5 m and moment of inertia 96.39 kgm2. The merry-go-round rotates with an angular velocity of 2.7 rad/s. What radial force does the child have to exert to stay on the merry-go-round?

The child then walks towards the center of the merry-go-round and stops at a distance 0.555 m from the center. Now what is the angular velocity of the merry-go-round?
