Aspace-walking astronaut has become detached from her spaceship! she's floating in space with her handy tool belt attached to her waist, thinking about how she might get back to the ship, which she can see 50 m from her current location. how can she get back to the ship? use language from the laws of motion in your answer.

Every action has a reaction, and an object in motion tends to stay at motion without outside forces affecting it.

So, she can get back by throwing her tool belt very hard in the opposite direction of the ship. The very hard throw in the direction opposite to the ship will have an equal and opposite reaction force towards the ship. She will then keep moving towards the spaceship at a constant speed because in space there is no air friction.
