The Newton's law which best describes what Taylor felt on the roller coaster is: A. Newton's First Law (Inertia) because there is no net force acting on Taylor.
Newton's First Law of Motion is also referred to as Law of Inertia and it states that an object (physical body) in motion would continue in its state of motion at continuous velocity (same speed and direction) or if at rest, it will remain at rest unless it is acted upon by an external force.
This ultimately implies that, inertia describes the tendency of a physical object to continue in its state of motion or remain at rest, when there is no net force acting on it.
In this scenario, Taylor felt like he was floating because there is no net force acting on him in accordance with Newton's First Law (Inertia).
