Physics

Object A is moving due east, while object B is moving due north. They collide and stick together in a completely inelastic collision. Momentum is conserved. Object A has a mass of mA = 17.0 kg and an initial velocity of VoA = 8.15 m/s, due east. Object B, however, has a mass of mB = 28.0 kg and an initial velocity of VoB = 4.85 m/s, due north. Find the magnitude of the final velocity of the two-object system after the collision.
