You are in space watching the two astronauts at rest in your frame of reference. They have identical mass, connected by a 12-m long cable, holding a heavy canister giving the center of mass to be two meters from Astronaut X. Astronaut X throws the canister to Y who catches it. How far will Astronaut move from his original position?​
