Chapter , Problem 29(choose chapter or problem)
In the instant of Fig. 11-41, two particles move in an xy plane. Particle P1 has mass 6.5 kg and speed v1 ! 2.2 m/s, and it is at distance d1 ! 1.5 m from point O. Particle P2 has mass 3.1 kg and speed v2 ! 3.6 m/s, and it is at distance d2 ! 2.8 m from point O. What are the (a) magnitude and (b) direction of the net angular momentum of the two particles about O?

QUESTION:
In the instant of Fig. 11-41, two particles move in an xy plane. Particle P1 has mass 6.5 kg and speed v1 ! 2.2 m/s, and it is at distance d1 ! 1.5 m from point O. Particle P2 has mass 3.1 kg and speed v2 ! 3.6 m/s, and it is at distance d2 ! 2.8 m from point O. What are the (a) magnitude and (b) direction of the net angular momentum of the two particles about O?
ANSWER:Step 1 of 3 a) The angular momentum of particle-1 is given by, Particle-1 moves in the x-direction with velocity, The particle-1 is at a distance in the y-direction from the origin, The mass of particle-1, So, The angular momentum of particle-2 is given by, Particle-2 moves in the y-direction with velocity, The particle-2 is at a distance in the x-direction from the origin, The mass of particle-2, So,
