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 = 17.9 kg and an initial velocity of = 8.82 m/s, due east. Object B, however, has a mass of mB = 28.9 kg and an initial velocity of = 4.01 m/s, due north. Find the (a) magnitude and (b) direction of the total momentum of the two-object system after the collision.
