My question is: You and your 100 kg partner are stranded in space 100m from your spaceship, you are running out of air and you have no equipment at all to help you get back. You are fine but your partner is badly injured and unable to move at all. Your partner is directly between you and the ship.
Using the concepts of conservation of linear and angular momentum, explain how you could get back to your spaceship in a reasonable degree of control facing towards it so that you can fly the spacecraft to retrieve your partner.
Any help would be greatly appreciated! Thanks in advance!
