A long uniform rod of length 4.76 m and mass 5.48 kg is pivoted about a horizontal, frictionless pin through one end. The rod is
released from rest in a vertical position as in the figure.
At the instant the rod is horizontal, find its angular speed. The acceleration of gravity is 9.8 m/s2 . Answer in units of rad/s.
At the same instant find the magnitude of its angular acceleration. Answer in units of rad/s2.
Still at the same instant find the magnitude of the acceleration of its center of mass. Answer in units of m/s2.
Finally, find the magnitude of the reaction force at the pivot (still at the same moment). Answer in units of N.
