A system consists of three identical 9-kg particles A, B, and C. The velocities of the particles are, respectively, vA = vAj, vB = vBi, and vC = vCk, and the magnitude of the linear momentum L of the system is 45 kg ?? m/s. Knowing that HG = HO, where HG is the angular momentum of the system about its mass center G and HO is the angular momentum of the system about O, determine

(a) The velocities of the particles,

(b) The angular momentum of the system about O.
