(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

An 93.0 spacewalking astronaut pushes off a 620 satellite, exerting a 120 force for the 0.470 it takes him to straighten his arms

2. Relevant equations

FA on S=FS on A

Xf=Xi+Vi[tex]\Delta[/tex]t+1/2a([tex]\Delta[/tex]t)^{2}

Those are the equations I think I use. And initial velocity should be zero, also for time I subtracted the time of the astronaut pushing off the total time

3. The attempt at a solution

I found the acceleration of the astronaut to be 1.29

and the acceleration of the satellite to be 0.194

Then I tried to fill those into the kinematic equations but I got a way large answer. I just need some guidance on where to start and such.
