4.A physical pendulum made from a uniform rod of mass 3.0 kg and length 1.0 mswings about an axis that passes through one end of the rod and is perpendicular to the planeof 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,find the acceleration of the elevator and whether the elevator is moving upward or downward.

This time the pendulum is 1.37 m long. Suppose you start with the pendulum hanging vertically, at rest. You then give it a push so that it starts swinging with a speed of 1.12 m/s. What maximum angle (in degrees) will it reach, with respect to the vertical, before falling back down? 7.0 degrees 29.9 degrees 23.8 degrees 17.6 degrees
Most injuries to the shoulder will require rehab and physical therapy. Pendulum exercises are a great way to increase strength and improve flexibility and range of motion in an injured shoulder. Here, the patient bends forward until their back is horizontal. The injured arm is hung vertically downward and is allowed to swing freely back and forth like a pendulum (see the figure). Treat the arm (length of 69 cm) in the figure as a physical pendulum – a uniform rod rotating about an axis through one of its ends – and calculate the period of the arm’s small oscillations.
Two pendula are shown in the figure. Each consists of a solid ball with uniform density and has a mass M. They are each suspended from the ceiling with massless rod as shown in the figure. The ball on the left pendulum is very small. The ball of the right pendulum has radius 1/2 L. L = 1.6 m Find the period T of the left pendulum for small displacements in s. Find the period T of the right pendulum for small displacements in s.

4. After landing on an unfamiliar planet, a space explorer constructs a simple pendulum of length 49.0 cm . The explorer finds that the pendulum completes 90.0 full swing cycles in a time of 145s. What is the magnitude of the gravitational acceleration on this planet?
A coin having a mass of m = 12 g, a thickness of h = 0.17 cm, and a radius of r = 1.5 cm has a small hole drilled through it so that it can be suspended from a thin wire and worn as an earring or pendant. The hole is at a distance of 7/8 r from the center of the coin as shown above. When suspended from this hole, the coin is a physical pendulum that swings back and forth with this hole as its axis of rotation. Assuming that the hole does not appreciably change the center of mass of the coin, determine the period of this physical pendulum.
