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 = 17.5 kg and an initial velocity of v0A = 7.95 m/s, due east. Object B, however, has a mass of mB = 28.0 kg and an initial velocity of v0B = 4.95 m/s, due north. Find the direction of the final velocity of the two-object system after the collision. o north of east.
