1. The problem statement, all variables and given/known data An astronaut has been left outside the space station, her back towards the station. The astronaut is not rotating (angular momentum ~ L = 0) and cannot reach anything. Is it possible for the astronaut to rotate herself into facing the space station? 2. Relevant equations Conservation of angular momentum 3. The attempt at a solution I think that the astronaut cannot rotate herself only by moving. So the answer would be no. She could maybe throw something from her backpack (if she has something) to change her angular moment.
