A bug of a known mass m stands at a distance dfrom the axis of a non-uniform spinning disk with radius rand unknown rotational inertia I that is rotating atfi revolutions per second. After the bug walksout to the edge of the disk and stands there, the disk rotates atff revolutions per second.
a. Determine the rotational inertia of the non-uniform disk.
b. Determine the change of kinetic energy in going from theinitial to the final situation for the total bug-disk system.
