A Federation starship (7.5 multiplied by 106 kg) uses its tractor beam to pull a shuttlecraft (5.0 multiplied by 104 kg ) aboard from a distance of 12 km away. The tractor beam exerts a constant force of 4.0 multiplied by 104 N on the shuttlecraft. Both spacecraft are initially at rest. How far does the starship move as it pulls the shuttlecraft aboard?
