A 62.3 kg spacewalking astronaut pushes off a 669.0 kg satellite, exerting a 174.0 N force for the 0.435 s it takes him to straighten his arms. How far apart are the astronaut and the satellite after 1.73 min?

-

P = F*t = 75.69 N∙s

Va = P/m = 1.215 m/s
Vs = P/M = 0.113 m/s

V = VA+Vs = 1.328 m/s

D = V*T = 1.328*1.73*60 = 137.86 m
