Chapter 11, Problem 57AP

Native people throughout North and South America used a bola to hunt for birds and animals. A bola can consist of three stones, each with mass m, at the ends of three light cords, each with length . The other ends of the cords are tied together to form a Y. The hunter holds one stone and swings the other two above his head (Figure P11.41a, page 308). Both these stones move together in a horizontal circle of radius 2 with speed v0. At a moment when the horizontal component of their velocity is directed toward the quarry, the hunter releases the stone in his hand. As the bola flies through the air, the cords quickly take a stable arrangement with constant 120-degree angles between them (Fig. P11.41b). In the vertical direction, the bola is in free fall. Gravitational forces exerted by the Earth make the junction of the cords move with the downward acceleration g . You may ignore the vertical motion as you proceed to describe the horizontal motion of the bola. In terms of m, , and v0, calculate (a) the magnitude of the momentum of the bola at the moment of release and, after release, (b) the horizontal speed of the center of mass of the bola, and (c) the angular momentum of the bola about its center of mass. (d) Find the angular speed of the bola about its center of mass after it has settled into its Y shape. Calculate the kinetic energy of the bola (e) at the instant of release and (f) in its stable Y shape. (g) Explain how the conservation laws apply to the bola as its configuration changes. Robert Beichner suggested the idea for this problem.

A conical pendulum consists of a mass of 0.5 kg attached at one end of a sting. The other end is fixed. As the mass moves in a circular path of radius 0.7 m, the string traces out the surface of a cone. What is the angle that the string makes with the ceiling?
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?
Chapter 10, Problem 069 In the figure, a small disk of radius r=4.00 cm has been glued to the edge of a larger disk of radius R=7.00 cm so that the disks lie in the same plane. The disks can be rotated around a perpendicular axis through point O at the center of the larger disk. The disks both have a uniform density (mass per unit volume) of 1.40 x 103 kg/m3 and a uniform thickness of 6.00 mm. What is the rotational inertia of the two-disk assembly about the rotation axis through O? Number Units the tolerance is +/-2% Click if you would like to Show Work for this question: Open Show Work
