Adhesive capsulitis, also known as a frozen shoulder, is a condition that affects the motion of the shoulder joint. The articular shoulder capsule becomes inflamed, stiff, and restricts a person’s mobility. Physical therapy provides one course of treatment for a frozen shoulder. One of the exercises often performed is the pendulum. Here, the patient bends forward and lets the injured arm hang downward and swing freely like a pendulum. The patient slowly swings their arm in a circular motion, for say 10 cycles, and then switches direction and completes 10 more. The patient may hold a light weight dumbbell while performing this motion, or just use an empty hand. Imagine the situation shown in the figure. A patient is moving a 7.0-lb (3.2-kg) dumbbell at constant speed and completes one circular motion of radius 0.40 meters in 1.40 s. What is the angle in degrees?
A thin rod of length 1.3 m and mass 190 g is suspended freely from one end. It is pulled to one side and then allowed to swing like a pendulum, passing through its lowest position with angular speed 3.03 rad/s. Neglecting friction and air resistance, find (a) the rod's kinetic energy at its lowest position and (b) how far above that position the center of mass rises.
A thin rod of length 0.632 m and mass 66.5 g is suspended freely from one
end. It is pulled to one side and then allowed to swing like a pendulum,
passing through its lowest position with angular speed 1.35 rad/s.
Neglecting friction and air resistance, find (a) the rod's kinetic energy at its
lowest position and (b) how far above that position the center of mass rises.
