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?

One simple way to measure the moment of inertia of an irregular object is shown in the diagram. The object is mounted on a frictionless axis. A light string is wrapped around the object, passes over a light pulley (so it has negligible moment of inertia itself), and then connected to mass M = 40.6 kg. The system is released from rest. After mass M has fallen distance 4.05 m it is moving 2.67 m/s and the object has reached...

Moment of Inertia/Conservation of Angular Momentum 10) Consider a cat in free-fall, as shown above (assume no external torques act upon it). As it falls, the cat has an initial angular velocity of: o 1.6 rad/s, and an initial moment of inertia of: In=7.5x 10 kgm. If the cat extends its legs so that its moment of inertia increases to I nal12.0x10 kgm, what would be the cat's final angular velocity?
