In the instant of the figure, two particles move in an xy
plane. Particle p_1 has a mass of 7.5 kg and speed of v_1=3.53 m/s,
and it is at a distance d_1=6.61 m from point O. Particle P_2 has a
mass of 2.10 kg and speed v_2=4.27 m/s, and it is at a distance of
d_2=6.19m from point O. What is the magnitude of the net angular
momentum of the two particles about O?
