1. The problem statement, all variables and given/known data Outside the International Space Station, a 60 kg astronaut holding a 4.0 kg object (both initially at rest) throws the object at 10 m/s relative to the space station. A 50 kg astronaut, initially at rest, catches the object. What is the speed of separation of the two astronauts? 2. Relevant equations p = mv FΔt = Δp Law of Cons. of Momentum Pi = Pf 3. The attempt at a solution Pi = Pf (4)(10) = (50)(v) v = 0.8 m/s which is wrong :( not sure how to approach this question, any help please? thank you!
