Question

A child is standing on the edge of a merry-goround that has the
shape as a solid disk, as shown in the figure below The mass of the
child is 40 kilograms The merry-go-round has a mass of 200
kilograms and a radius of 2 5 meters, and it is rotating with an
angular velocity of ω = 2 0 radians per second The child then
walks slowly toward the center of the merry-go-round What will be
the final angular velocity of the merry-go-round when the child
reaches the center ?
