A disc of moment of inertia 3.00 kgm2 is rotating with angular velocity 2.00 rad/s about an axis perpendicular to its plane and passing through its centre. Another disk (which is not rotating) of moment of inertia 5.00 kgm2 is gently placed over it. Finally, the two discs rotate with the same angular velocity around the common rotational axis. The new angular velocity of the combined disc (in rad/s) is ?

A uniform solid disc, whose moment of inertia is unknown, is rotating at an angular velocity of 500 rpm. Later it falls on another solid disc that is at rest and that its moment of inertia is of 2.50 kg * m2. The final speed with which both rotate is 170 rpm. Determine the moment of inertia of the disc.

Two disks are rotating about the same axis. Disk A has a moment of inertia of 4.45 kg.m2 and an angular velocity of +4.87 rad/s. Disk B is rotating with an angular velocity of -7.28 rad/s. The two disks are then linked together without the orques, so that they rotate as a single unit with an angular velocity of -3.59 rad/s. The axis of rotation for this unit is the same as that for the separate disks. What is the...

A solid disk rotates in the horizontal plane at an angular velocity of 0.0612 rad/s with respect to an axis perpendicular to the disk at its center. The moment of inertia of the disk is 0.134 kg·m2. From above, sand is dropped straight down onto this rotating disk, so that a thin uniform ring of sand is formed at a distance of 0.398 m from the axis. The sand in the ring has a mass of 0.509 kg. After all...

1. A disk whose moment of inertia is 2 kgm2 is rotating at 120 rad/s. This disk is pressed against a similar disk (with the same inertia) that is able to rotate freely, but initially at rest. The two disks stick together and rotate as a unit. (a) Find the final angular velocity of the combination. (b) How much energy was lost to friction when the disks were brought together?
