An astronaut is outside of her spaceship with no jetpack or tie line, repairing the engine. Suddenly, she finds herself away from the ship, and only has a wrench in her hands. As she stares at her ship, she tries to think of a way to get back. Since there is nothing to push off from, she thinks that she may be lost forever, but suddenly remembers the wrench. Using the wrench, how can she get back to the ship? How does this demonstrate Newtonβs 1st Law?

1. by throwing the wrench away from the spaceship , she will give herself momentum towards the ship

to me , this seems more like the 3rd law ... action/reaction

2. 1st law says that unless a force acts, she will stay away from the ship.
