A Federation starship (2.20 ×106 kilogram) uses its tractor beam to pull a shuttlecraft (2.20 × 104 kilogram) aboard from a distance of 12 kilometer away. The tractor beam exerts a constant force of 4.0 × 104 Newton on the shuttlecraft. Both spacecraft are initially at rest. Determine how far does the starship move as it pulls the shuttlecraft aboard?
