The 25-lb slender rod has a length of 6 ft. Using a collar of negligible mass, its end A is confined to move along the smooth circular bar of radius 3V2 ft. End B rests on the floor, for which the coefficient of kinetic friction is µg = 0.4. If the bar is released from rest when = 30°, determine the angular acceleration of the bar at this instant. 6 ft 3√2h
