Homework Statement
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?
Homework Equations
p = mv
FΔt = Δp
Law of Cons. of Momentum
Pi = Pf
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!
