released from rest in a vertical position as in the figure.

(A)

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.

(B)

At the same instant find the magnitude of its angular acceleration. Answer in units of rad/s2.

(C)

Still at the same instant find the magnitude of the acceleration of its center of mass. Answer in units of m/s2.

(D)

Finally, find the magnitude of the reaction force at the pivot (still at the same moment). Answer in units of N.
