    Rescuing a Stranded Partner in Space: Utilizing Conservation of Momentum

    ok thanks...this is really frustrating me...im supposed to incorporate the laws of angular and linear momentum but don't know how. my prof says it isn't easy, so there must be a trick to it maybe...

    Rescuing a Stranded Partner in Space: Utilizing Conservation of Momentum

    Ok, this is true. Now what exactly could you and the partner do to create a torque to start the spinning. Remember, I need to be facing the ship when I get there and I need to be in control of my speed (preferably slowing down). Thanks :)!

    Rescuing a Stranded Partner in Space: Utilizing Conservation of Momentum

    thanks whozum. can you just start spinning in space tho? wouldn't you have to initiate it somehow? #3 is asking if the angular momentum is shown by the big arrow, what direction is the guy twisting and somersaulting and name 2 ways to stop the rotation. thanks again!

    Rescuing a Stranded Partner in Space: Utilizing Conservation of Momentum

    Well youre facing the ship, but your partner is between you and the ship, facing you. I thought if you could somehow spin with him to trade places with him it might work, but as it stands, he is in your way. Any help is appreciated! Thanks!
