1. The problem statement, all variables and given/known data You have been hired to check the technical correctness of an upcoming sci-fi thriller film. The movie takes place in the space shuttle. In one scene, an astronaut's safety line is damaged while she is on a space walk, so she is no longer connected to the space shuttle. She checks and finds that her thruster pack has also been damaged and no longer works. She is 200 m from the shuttle and moving with it (i.e., she is not moving with respect to the shuttle). She is drifting in space with only 4 minutes of air remaining. To get back to the shuttle, she decides to unstrap her 10-kg tool kit and throw it away with all her strength, so that it has a speed of 8 m/s relative to her. In the script, she survives, but is this correct? Her mass, including her space suit, is 80 kg. 2. Relevant equations m1 * Δv1 = m2 * Δv2 (I think (law of conservation of momentum?)) Time = Distance / Velocity 3. The attempt at a solution So I did: 80 * x = 10 * 8 (Law of conservation of momentum?) x= 1 m/s Time = 200 / 1 = 200 seconds So she would make it with 40 seconds remaining in air, but this seems way to easy and very very wrong.
