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...
Problem 10 Two disks are mounted on low-friction bearings on a common shaft. The first disc has rotational inertia I and is spinning with angular velocity w. The second disc has rotational inertia 2I and is spinning in the same direction as the first disc with angular velocity 2 o as shown. The two disks are slowly forced toward each other along the shaft until they couple and have a final common angular velocity of:
Three disks are spinning independently on the same axle without friction. Their respective rotational inertias and angular speeds are I,? (clockwise); 2I,3? (counterclockwise); and 4I,?/2 (clockwise). The disks then slide together and stick together, forming one piece with a single angular velocity. What will be the direction and the rate of rotation ?net of the single piece?
(4) A playground ride, known as merry-go-round, consists of a disk with a mass of 40.0 kg and a radius of 1.80 m mounted on a frictionless axle. The frictionless axle is a vertical cylinder of radius kg, and has the same rotational axis as the disk. A child with a mass of 3.50 m/s on a line tangential to the outer rim of the disk and jumps onto the outer edge of the ride while it is at rest...
1. Three children are riding on the edge of a merry‑go‑round that has a mass of 105 kg and a radius of 1.80 m. The merry‑go‑round is spinning at 22.0 rpm. The children have masses of 22.0, 28.0, and 33.0 kg. If the 28.0 kg child moves to the center of the merry‑go‑round, what is the new angular velocity in revolutions per minute? Ignore friction, and assume that the merry‑go‑round can be treated as a solid disk and the children...
(1096) Problem S: A merry-go-round is a playground ride that consists of a large disk mounted to that it can freely rotate in a horizontal plane. The merry-go-round shown is initially at rest, has a radius R-1.1 meters, and a mass M- 221 kg. A small boy of mass m 49 kg runs tangentially to the merry-go-round at a speed of v1.7m/s, and jumps on.

the question is in last picture. i provided the lab content... I need guidance. thank you. INVESTIGATION 10 ROTATIONAL MOTION OBJECTIVE To determine the moment of inertia I of a heavy composite disk by plotting measured values of torque versus angular acceleration. THEORY Newton's second law states that for translational motion (motion in a straight line) an unbalanced force on an object results in an acceleration which is proportional to the mass of the object. This means that the heavier...
