An object (A) of mass m A = 28.0 kg is moving in a direction that makes angle of 50° south of west with a speed v A = 4.90 m/s, while object (B) of mass m B = 18.0 kg is moving due south with a speed v B = 7.85 m/s. The two objects collide and stick together in a completely inelastic collision. Find the magnitude of the final velocity of the two-object system after the collision.
