2 m/sec in the direction of travel of Spaceship 2, assuming they are both in frictionless outer space.

1800 kg-m/sec 600 kg x 3 meters/sec (in the direction spaceship 2 was headed). Since the first spaceship had all the initial momentum, only the velocity of the combined mass will change.

momentum must be conserved momentum = mass*velocity initially momentum = 150*6 +150*0 = 900 kgms-1 final momentum = 300*combinedvelocity = 900 so the final velocity must be 3 ms-1
