Comparison of initial states for two rocks released at distance R from a planet.
Comparison of initial states for two rocks released at distance R from a planet.
A satellite is in a circular orbit of radius R around a planet of mass M. A rock is released from the satellite in two different scenarios.

Scenario 1: The rock is released such that it is initially at rest relative to the satellite.
Scenario 2: The rock is launched backward relative to the satellite's motion such that it has no initial velocity relative to the center of the planet.

Which of the following correctly compares the magnitude of the initial acceleration of the rock in the two scenarios and provides a valid justification for its subsequent motion?
