Want this question answered?
The action force is your hand moving back. The reaction force is the ball moving the other way.
Any object moving or stationary that is on the ground is subjected to a normal/reaction force upwards.
The answer is reaction. A simple example is you standing on the ground. You are not moving or accelerating (in our reference frame). You are pushing down against the ground with a force (the action) equal to your weight. The ground pushes back up (opposite direction) with an equal force (the reaction force).
It will not until an unbalanced force acts on it. Another force is used against it creating an equal and opposite reaction.(Newton's Third Law)
Reaction Force

he is holding a stack of books on his back but he is not moving

Actually a force without another reaction force is something that will always be moving or staying motion because theres no reaction to stop it but theres no such thing as that so ya......
Resistance from air.
u have to have the window rolled down about 4 inches. If the window is stuck up force it down and you can access 2 bolts holding it to the window. Only force it if you plan to replace the regulator.
Rockets have an exhaust of hot gas, moving rapidly away from the rocket, which is the action, and the reaction is that the rocket is propelled forward.
If there's nothing else holding it back, then any force will move any mass. Andonce you get it moving, you don't need any force at all to keep it moving.
according to voiume 1 physics, by resnick and halliday cart- horse paradox is discussed. the point of application of force and action-reaction pairs have to be considered at the moment of moving.
Reaction force that is equal and opposite to thrust force from the rocket's engine.
Gravity, in balance with centripetal reaction force.
The answer is reaction. A simple example is you standing on the ground. You are not moving or accelerating (in our reference frame). You are pushing down against the ground with a force (the action) equal to your weight. The ground pushes back up (opposite direction) with an equal force (the reaction force).
