What is the ratio of its translational kinetic energy to its rotational kinetic energy (about an axis through its center of mass)? Angular Momentum and Newton's Second Law 2. A 2.0-kg particle is moving at a velocity of 3.0-1.0 +4.0 km/s when it is at (3.0 m, 2.0 m, 4.0 m). (a) Find its angular momentum about the origin O. (b) Find its angular momentum about a point A with coordinates (1.0 m, 3.0 m, - 1.0 m). The Angular Momentum of a Rigid Body; Conservation of Angular Momentum about an 3. A uniform disk has radius R and mass M is spinning with an angular velocity axis perpendicular to its face and is at a distance R/3 from the center. Determine the angular momentum of the disk. 1.
