A system consists of three identical 19.32-lb particles A, B, and C. The velocities of the particles are, respectively, vA = vA j, vB = vB i, and vC = vC k. Knowing that the angular momentum of the system about O, expressed in ft ∙ lb ∙ s is HO = -1.2k, determine

(a) The velocities of the particles,

(b) The angular momentum of the system about its mass center G.
