## Homework Statement

A 63.8kg spacewalking astronaut pushes off a 678.0kg satellite, exerting a 156.0N force for the 0.870s it takes him to straighten his arms. How far apart are the astronaut and the satellite after 8.67min?

## Homework Equations

## The Attempt at a Solution

I tried just finding the acceleration of the satellite using Fnet=ma and then using that acceleration to place it into d=1/2at^2 (assuming the satellite was at rest) The answer came up into the thousands so I knew I did something wrong. I have no idea of how to start this question so it'd be great if someone could help out!

Thanks!
