Calculate the moment of inertia (units of kg·m2) about an axis for a rotating body with a total mass of 100 kg, the moment of inertia about its COG of 2 kg·m2, and a COG located 0.1 m away from the axis of rotation.

A man stands on a platform that is rotating (without friction) with an angular speed of 0.364 rev/s; his arms are outstretched and he holds a brick in each hand. The rotational inertia of the system consisting of the man, bricks, and platform about the central axis is 7.01 kg·m2. If by moving the bricks the man decreases the rotational inertia of the system to 1.47 kg·m2, (a) what is the resulting angular speed of the platform and (b) what is the ratio of the new kinetic energy of the system to the original kinetic energy?

Ques:

1. What is the moment of inertia of a 2.50kg, 30.0-cm-diameter disk for rotation about an axis through the center?

2. What is the moment of inertia of the disk for rotation about an axis through the edge of the disk?

A playground carousel is free to rotate about its center on frictionless bearings, and air resistance is negligible. The carousel itself (without riders) has a moment of inertia of 130 kg·m2. When one person is standing at a distance of 1.50 m from the center, the carousel has an angular velocity of 0.650 rad/s. However, as this person moves inward to a point located 0.750 m from the center, the angular velocity increases to 0.790 rad/s. What is the person's mass?
