Question
a space-walking astronaut of total mass 148 kg exerts a force a force of 265 N on a free-floating satellite of mass 635 kg, pushing it in the positive x-direction. What is the reaction force exerted by the satellite on the astronaut? Calculate accelerations of the astronaut and the satellite.a space-walking astronaut of total mass 148 kg exerts a force a force of 265 N on a free-floating satellite of mass 635 kg, pushing it in the positive x-direction.

Explanation / Answer
reaction force exerted by the satellite on the astronaut = 265 N
( Newton's third law : For every action, there is an equal and opposite reaction)
b) F = ma
=> 265 = 148*a ( for astronaut )
=> a = 1.79 m/s^2
c) 265 = 635*a ( for satellite)
=> a = 0.4173 m/s^2
