Find what the angular velocity when man reaches the edge

Reference no: EM13681539

A man of mass 74 kilogram stands at the center of a rotating merry-go-round platform of radius 3.2 meter and moment of inertia 990 kg•m². The platform rotates without friction with angular velocity 1.6 rad/s. The man walks radically to the edge of the platform.

a) Find the angular velocity when man reaches the edge?

b) Find the rotational kinetic energy of the system of platform plus man before and after the person's walk?
