A physical pendulum made from a uniform rod of mass 3.0 kg and length 1.0 m 4. swings about an axis that passes through one end of the rod and is perpendicular to the plane of the swing. What is the angular frequency of the pendulum? What is the period of the pendulum if it undergoes free fall? Explain. If it is known that the period of the pendulum is 1.5 s when it is placed in an elevator, (b) find the acceleration of the elevator and whether the elevator is moving upward or downward.
