A Federation starship (2.0 X 10^6 kg) uses its tractor beam to pull a shuttlecraft (2.0 X 10^4 kg) aboard from a distance of 10km away. The tractor beam exerts a constant force of 4.0 X 10^4N on the shuttlecraft. Both spacecraft are initially at rest. How far does the spaceship move as it pulls the shuttlecraft aboard?

Answer:

Well if this was in space it would be infinite distance because the ships aren’t being touched by an outside force so it would go on forever. I think.

I got like 198 m but I might be wrong.
