A child sits in the center of a merry-go-round. The mass of the child is m=25 kg and assume the relative size of the child is small. The merry-go-round is a solid disk of radius 1.5 m and mass M=175 kg. The initial angular speed of the merry-go-round is ω0=1.5rad/s. (ldisk =1/2MR2, Ipt object =mR2 ) a) Determine the total initial rotational inertia of the system. b) Determine the initial angular momentum of the system. Now let the child walk to the outer edge of the merry-go-round while it is rotating c) Determine the final total inertia. d) Determine the final angular momentum. e) Determine the final angular speed. f) Determine the total work done by the child while walking to the edge from the center.
