Physics homework problem?

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 m of mA = 17.6 kg and an initial velocity of v0A = 8.37 m/s, due east. Object B, however, has a m of mB = 28.1 kg and an initial velocity of v0B = 4.13 m/s, due north. Find the (a) magnitude and (b) direction of the total momentum of the two-object system after the collision.
