1. you and your partner are astronauts wearing 10kg space suits, you are drifting away from the space ship 0.1m/s and your partner is stationary directly between you and the space ship which is 100m away from your partner. The ship cannot move and no ones aboard to get you. You are fine but your partner is badly injured and unable to move! Oh and your holding a 20kg tool box. -->I need to get my injured partner and I to the space ship, I need to explain using conservation of linear and angular momentum how Im going to be able to do this...I was thinking pushing off the toolbox in a way? It would prevent me from going back 0.1m/s for sure and possibly get me to my partner, perhaps position myself in somersaulting postion? Not too sure!
