*56. D One end of a thin rod is attached to a pivot, about which it can rotate without friction. Air resistance is absent. The rod has a length of 0.80 m and is uniform. It is hanging vertically straight downward. The end of the rod nearest the floor is given a linear speed vo, so that the rod begins to rotate upward about the pivot. What must be the value of v,, such that the rod comes to a momentary halt in a straight-up orientation, exactly opposite to its initial orientation?
