Momentum is mass multiplied by velocity. The momentum of the two ships would be 300 x 2 = 600 kgm/s and 300 x 1 = 300 kgm/s. So the combined momentum of the two ships would be 900 kgm/s.
Momentum = (speed) times (mass).Spaceship-1 has no momentum, since its speed is zero. The combined momentum is just the momentum of Spaceship-2.Momentum of Spaceship-2 = (m V) = 300 x 4 = 1,200 kg-meters

Momentum = (mass) x (velocity), in the same direction as the velocity.Spaceship-1 . . . Momentum = (300) x (3) = 900 kg-m/sec, in some direction.Spaceship-2 . . . Momentum = (300) x (2) = 600 kg-m/sec, in the same direction.Their combined momentum = 1,500 kg-m/sec, in their common direction.

Momentum = mass x speedSince Spaceship-#1 is not moving, it has no momentum. Their combined momentumis that of Spaceship-#2 alone.Momentum = mass x speed = 200 x 10 = 2,000 kilogram-meters per second.
