Two disks are mounted (like a merry-go-round) on low-friction bearings on the same axle and can be brought together so that they couple and rotate as one unit. The first disk, with rotational inertia 3.25 kg m2 about its central axis, is set spinning counterclockwise (which may be taken as the positive direction) at 181 rev/min. The second disk, with rotational inertia 7.95 kg.m2 about its central axis, is set spinning counterclockwise at 879 rev/min. They then couple together. (a)...

Two disks are mounted (like a merry-go-round) on low-friction bearings on the same axle and can be brought together so that they couple and rotate as one unit. The first disk, with rotational inertia 3.00 kg m about its central axis, is set spinning counterclockwise at 550 rev/min. The second disk, with rotational inertia 6.40 kg m about its central axis, is set spinning counterclockwise at 800 rev/min. They then couple together. (a) What is their angular speed after coupling?...

6. (9pt) A disk and a ring are mounted on low-friction bearings on the same axle and can be brought together so that they couple and rotate as one unit. The mass is uniformly distributed throughout the objects. The disk and the ring both have a radius of 10cm and a mass of 4kg. The objects are set spinning about their central axis, the disk at 400rev/min in clockwise direction and the ring at 800rev/min in the opposite direction. They...

Two disks of identical mass but dif- ferent radii (r and 21) are spinning on frictionless bearings at the same angular speed w, but in opposite directions (Fig- ure 10-46). The two disks are brought slowly together. The re- sulting frictional force between the surfaces eventually brings them to a common angular velocity. What is the magnitude of that final angular velocity in terms of w.? 00 00

A physics professor sits on a stool mounted to a low friction rotating platform while holding a 2.8 kg mass in each hand. When his arms are fully extended away from his body, the masses are each 1.15 m from the central vertical axis of rotation. A helpful student pushes on the masses as the professor begins spinning faster and faster until the professor rotates with an angular velocity of 0.9 rad/s. The moment of inertia of the professor and...

Problem 1 Two identical pucks, each of inertia m, are connected to a rod of length 2r and negligible inertia that is pivoted about its center (that is, there is some sort of pin though its center, around which it can rotate without friction). A third puck of inertia m/2 strikes one of the connected pucks perpendicular to the rod with a speed vi. Assume the collision is elastic. (a) Draw a diagram of the situation, clearly labeling the direction...

3-axis center of mass FIGURE 8.24 Problem 20: (Tippe top) This simple device appears to defy the laws of classical mechanics. Start it spinning, and it eventually inverts, raising its center of mass to a higher position, where it spins happily until it runs down. We will examine this strange behavior qualitatively here. The top has a mass M and radius R. The center of mass is a distance a from the center of the sphere as shown in Figure...

PHYSICS HOMEWORK # 26 NEWTON'S LAWS FIRST LAW & FRICTION 24. Two masses are sitting on a horizontal surface as shown to the right. The coefficient of sliding friction between these two masses and the horizontal surface is m-0.520. A string is attached to the end of mas m,8.00 kg. This string is then looped arounda pulley and is finally attached to the left vertical surface. The pulley is attached to mass m 12.0 kg as shown and then a...
