A stick of mass 18.4 kg and length 3.4 m is pinned at its center but is free to rotate (the moment of inertia of only the stick about its center equals (1 12)mL^ 2 ). A mass of 8.1 kg is permanently fixed to one end of the stick. If you hold up the end with the mass above the horizontal so that the stick makes an angle ɵ=56 3. with the vertical, What is the angular acceleration of the stick right after you let it go from that angle?
