In the instant of the figure, two particles move in an xy plane. Particle P1 has mass 3.63 kg and speed v1 = 8.40 m/s, and it is at distance d1 = 2.25 m from point O (the figure is not drawn to scale). Particle P2 has mass 6.64 kg and speed v2 = 1.92 m/s, and it is at distance d2 = 5.33 m from point O. What is the magnitude of the net angular momentum of the two particles about O? Number Units
