- Umb 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 1 (46.35 KiB) Viewed 52 times
umb" 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 2.40 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?
