Two astronauts are playing catch in a zero gravitational field. Astronaut 1 of mass m₁ is initially moving to the right with speed v₁. Astronaut 2 of mass m₂ is initially moving to the right with speed v2 > ₁. Astronaut 1 throws a ball of mass m with speed u relative to herself in a direction opposite to her motion. Astronaut 2 catches the ball. The final speed of astronaut 1 is vf, and the final speed of astronaut 2 is vf,2. ((m+m_1)*(v_1)+(m*u))/m_1 171. Vf₂1 = (m I m.)
