Question

A system consists of three identical 5-kg particles A, B, and C. Their position vectors (in meter) and velocity vectors (in m/s) are rA 0,0, 3 , v A v Aj , rB  2,2, 3 , vB  v B i , and rC  1,4, 0 , vC  v C k, respectively. Knowing that the angular momentum of the system about point O is HO 1.5k kg m 2s, determine (a) the velocities of the particles, (b) the angular momentum of the system about its center of mass G.

A system consists of three identical 5-kg particles A, B, and C. Their position vectors (in meter) and
velocity vectors (in m/s) are r, = (0,0,3), v
