An astronaut in a white space suit is shown floating in the vacuum of space. The astronaut's hands are pressed against a large, rectangular metallic satellite that has solar panels attached. Arrows indicate that the astronaut is pushing away from the satellite. The astronaut is labeled 'm_A' and the satellite is labeled 'm_S'.
An astronaut pushing a satellite in deep space.
An astronaut of mass \( m_A = 80 \text{ kg} \) is floating in space next to a large satellite of mass \( m_S = 800 \text{ kg} \). The astronaut and satellite are initially at rest relative to one another. The astronaut then pushes on the satellite, causing both to move apart. Which of the following correctly compares the magnitude of the force exerted by the astronaut on the satellite, \( F_{A \to S} \), to the magnitude of the force exerted by the satellite on the astronaut, \( F_{S \to A} \), and compares their resulting accelerations?
