Momentum = (mass) x (velocity), in the same direction as the velocity.
Spaceship-1 . . . Momentum = (150) x (0) = 0 kg-m/sec, in some direction.
Spaceship-2 . . . Momentum = (150) x (6) = 900 kg-m/sec, in the same direction.
Their combined momentum = 900 kg-m/sec, in their common direction.
2 m/s
The new speed for the combined masses will be one-half the original velocity of the moving spaceship, since the momentum is applied to a mass twice as large.

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.
The momentum of an object is given by the formula: momentum = mass x velocity. Therefore, the combined momentum of Spaceship 1 and Spaceship 2 after the collision would be the sum of their individual momentums. Since they have equal masses and are moving in the same direction, you can simply add their individual momentums to get the combined momentum.
Generally, no.
