A person stands on a uniformly rotating ...

A person stands on a uniformly rotating turn table with outstretched arms holding two identical weights. The moment of inertia of the system is `60 kgm^2`. When he brings the arms close to his body, the M.I. of inertia reduces to`58 kgm^2`. The angular speed of the system now becomes `3 rad s^-1`. Find the initial angular speed and the final K.E.
