Academics

A person of mass 79kg stands at the center of a rotating merry-go-round platform of radius 3.3m and moment of inertia 830kg*m^2. The platform rotates without friction with angular velocity 0.95rad/s . The person walks radially to the edge of the platform.

Part A Calculate the angular velocity when the person reaches the edge.

Part B Calculate the rotational kinetic energy of the system of platform plus person before and after the person's walk.
