Problem: A 2.00-kg rock has a horizontal velocity of magnitude 12.0 m/s when it is at point P in the figure (Figure 1). At this instant, what are the magnitude and direction of its angular momentum relative to point O? 

FREE Expert Solution

Angular momentum:

L=mvr·sinθ

The angle between v and r is

θ = 180 - 36.9 = 143.1°
