Afederation starship (8.5 ✕ 106 kg) uses its tractor beam to pull a shuttlecraft (1.0 ✕ 104 kg) aboard from a distance of 14 km away. the tractor beam exerts a constant force of 4.0 ✕104 n on the shuttlecraft. both spacecraft are initially at rest. how far does the starship move as it pulls the shuttlecraft aboard?

Force applied by the beam is given as

now the acceleration of starship is given as

acceleration of space craft will be given as

now the relative acceleration is given as

now the distance between them is d = 14000 m

now we can use kinematics to find the time to cover this distance

now we have to find the distance moved by starship

so it will move by 16.4 m distance
