The 25 kg-heavy, 6 m-long slender rod AB slides without friction on the ground and on the circular bar of radius 3\sqrt(2) m. The rod is left free from rest from the configuration shown in Figure 1, where \theta = 30 degrees. Determine the angular velocity and angular acceleration of the rod at the instant right before it becomes horizontal and its end A hits the ground. The acceleration of gravity is g = 9.81( m)/(s^(2)) Figure 1: A rod sliding without friction on the ground and one a circular bar.
