Astronaut and wrench

  1. Nov 21, 2004 #1
    This problem is driving me insane:
    An astronaut is initially at rest, at a distance x_1 from the spaceship. She hurls a wrench with a speed v, relative to the spaceship. Find the final distance x_2 between the spaceship and the wrench using some or all of the variables given.

    Only internal forces act upon system astronaut+wrench.
    Hence, since the C.M. of this system is at rest relative to the spaceship initially, it (the C.M) will remain at the same position throughout the period.
    That is, the C.M of astronaut+wrench will remain at the distance x1 from the spaceship.

    Aren't they looking for the final distance x_2 after the wrench was thrown? So wouldn't you need to first find x_1 and delta x to find x_2?

    I don't know how you're not getting the right answer.
    Post your work.
