A mаn stаnds оn а platfоrm that is rоtating (without friction) with an angular speed of 2.33 rev/s; his arms are outstretched and he holds a brick in each hand. The rotational inertia of the system consisting of the man, bricks, and platform about the central axis is 6.92 kg·m2. If by moving the bricks the man decreases the rotational inertia of the system to 1.96 kg·m2, what is the resulting angular speed in rad/s of the platform? (show all work)
