Is This Scenario Demonstrating Newton's Third Law of Motion?

[permapoop]

Let's say there's two people, A and B.

Person A hits person B and person A gets pushed back more than person B does.

Would be that be exhibiting Newton's Third Law of Motion of Newton's Second Law of Motion?

I think both.
How much A is pushed back and its acceleration after collision is given by II law, and III law says A is affected by its pushing against B.

Newtons II law is applied in cases only if there is acceleration( there must be net force available in a direction). Newton III law is applied in cases involving forces(independent of net force).

Your language is a little fuzzy. Does "gets pushed" mean "experiences a force"? If so, the situation you describe violates the third law of motion. It says that whenever one body applies a force to a second body, the second body applies a force of the same size but opposite direction on the first body. The pushes in the scenario have to be the same size.

If "gets pushed back more" means that Person A ends up a greater distance from the starting point than Person B, then the Second Law comes into play. Both people start at rest and end up moving, so each accelerated. If Person A moves farther in a given amount of time, he or she experienced a greater acceleration. It follows from the Second Law that he or she has a lesser mass than Person B.

This scenario would be exhibiting Newton's Third Law of Motion, also known as the Law of Action and Reaction. According to this law, every action has an equal and opposite reaction. In this case, person A's hit on person B is the action, and the force of person B pushing back on person A is the equal and opposite reaction. This is in accordance with Newton's Third Law of Motion. Newton's Second Law of Motion, also known as the Law of Force and Acceleration, states that the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass. While this law may also apply in this scenario, it is not the primary principle at play.
