moembntum is conserved.
62*.50+3200*V=0
V= - 31/3200 m/s the negative sign means to the right.
So if you are looking for the velocity of the spacecraft, it is .0096m/s to the right.
I have no idea why you put kg.
Question: A 62 kg astronaut floats outside a 3200 kg spacecraft. She's initially stationary with respect to the spacecraft. Then she pushes against the spacecraft and moves away at .50m/s to the left.
I got an answer of .0096kg from doing 62*.50/3200 but that is incorrect.
Could you help me with this? I'm not sure how to answer this question.
