A 24.5-kg child is standing on the outer edge of a horizontal
merry-go-round that has a moment of inertia of 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.
a. What is the moment of inertia of the child + merry go
round when standing at the edge?
b. What is the moment of inertial of the child + merry go
round when standing 1.10 m from the axis of rotation?
c. Find the angular velocity if the child moves to a new
position 1.10 m from the center of the merry-go-round.
d. What is the change in rotational kinetic energy between
the edge and 2.40 m distance?
