1. The problem statement, all variables and given/known data If an astronaut was in a weighless environment, sitting down and eating a meal, what would happen to the astronaut if the spacecraft decided at that moment to turn on the space craft's main engines and a) the astronaut was facing the engines? b) the astronaut's back was to the engine? 3. The attempt at a solution How would you even figure this out since you don't know what direction the spacecraft starts moving? I'm just really confused. Would the astronaut move in the opposite direction?
