Example 19.2 Angular Momentum and Circular Motion A particle of mass m moves in a circle of radius r at an angular speed ω about the z-axis in a plane parallel to the x-y plane passing through the origin O (Figure 19.5). Find the magnitude and the direction of the angular momentum L O relative to the origin. Figure 19.5 Example 19.2
