    Astronaut

    A 68.5 astronaut is doing a repair in space on the orbiting space station. She throws a 2.40 tool away from her at 3.60 relative to the space station.

    With what speed direction will she begin to move?

    i figured it would be 3.60 m/s in the opposite direction but this answer doesnt seem to be correct and im not sure exactly why

    any help would be appreciated thank you.

    This is a conservation of momentum problem. The astronaut's momentum will be -p, where p is the momentum of the tool. Momentum is m \bold{v}.
