Discover work done by skater pulling weights to his chest

Reference no: EM13659355

A skater body has rotational inertia 4.2 kg.m^2 with his fist held to his chest and 5.7 kg.m^2 by arm outstretched. The skater is twirling at 3.0 rev/s while holding a 2.5 kg-weight in all outstretched hand; the weights are .76 m from his rotational axis. Discover the work done by the skater pulling the weights to his chest?
