what would happen to the output force of
this system?

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

explanation:

to push or pull an object in a certain direction is known as force. a force in moving an object from one place to another.

force depends on the mass of an object. so, more is the mass of an object more will be the force required to move the object.

thus, we can conclude that the use of force to move an object is push or pull.
