Two astronauts are taking a spacewalk outside the International Space
Station. The first astronaut has a mass of 85.2 kg. The second has a mass of
65.4 kg. Initially, both astronauts have zero velocity relative to each other.
Then, the astronauts push against each other, giving the first astronaut a final
velocity of 1.2 m/s to the left. If the momentum of the system is conserved,
what is the final velocity of the second person?
