It varies greatly. It will depend on how far away it is from the object it's orbiting. If it is in a circular orbit around the Earth, its speed can be calculated by the formula:
speed = Squareroot(398600/(6371+altitude))
This will give you an answer in kilometers per second.
The massive speed and acceleration of the spaceship is so great, that they are able to escape Earth's gravitational pull. Then at around the correct altitute, they can orbit the Earth safely.

2 m/sec in the direction of travel of Spaceship 2, assuming they are both in frictionless outer space.
2,000 kg-m/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
2000
Multiply mass x velocity for each spaceship. Add the results.
1,800 kg-m/s
2,000 kg-m/s
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.
