Question

which of the following scenarios best illustrates newtons third law of motion?
a book remains at rest on a table
a car accelerates when the gas pedal is pressed
a swimmer pushes against the wall and moves forward
a ball rolling on a flat surface slows down due to friction

Explanation:

Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. When the swimmer pushes against the wall (action), the wall pushes back on the swimmer (reaction), causing the swimmer to move forward.

Answer:

A swimmer pushes against the wall and moves forward
