Conservation of angular momentum. A gear wheel is on a friction-less axis that is not in motion with a projectile being shot at the gear wheel perpendicular; the ball sticks to the wheel. Radius is 1.48 m; Mass is 2.0 kg; Velocity is 5.0 m/s; moment of Inertia is 100 kgm^2. Determine the fraction of mechanical energy lost in a rotational collision.

The physics students wish to test the law of conservation of angular momentum perform a completely inelastic collision between two discs. They attach disc 1 (from part 1) to the rotational sensor then give it a spin. After about 4 seconds, they drop disc 2 on top of disc 1. The whole process takes only ~10 seconds total. Use the rate of change of the single disc angular velocity and the duration of the collision to find a corrected value...

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?

A wheel is rotating freely at angular speed 600 rad/s on a shaft whose rotational inertia is negligible. A second wheel, initially at rest and with three times the rotational inertia of the first, is suddenly coupled to the same shaft. What is the angular speed of the resultant combination of the shaft and two wheels? What fraction of the original rotational kinetic energy is lost in the collision?
