A bug of a known mass m stands at a distance d from the axis of a non-uniform spinning disk with radius r and unknown rotational inertia I that is rotating at fi revolutions per second. After the bug walks out to the edge of the disk and stands there, the disk rotates at ff revolutions per second.

a. Determine the rotational inertia of the non-uniform disk.

b. Determine the change of kinetic energy in going from the initial to the final situation for the total bug-disk system.
