Aman stands at the center of a platform that rotates without friction with an angular speed of 3.95 rev/s. his arms are outstretched, and he holds a heavy weight in each hand. the moment of inertia of the man, the extended weights, and the platform is 12.5 kgm^2. when the man pulls the weights inward toward his body, the moment of inertia decreases to 2.5 kgm^2. what is the resulting angular speed of the platform?
