question 15 (1 point)
determine if the example is newtons 1st, 2nd, or 3rd law.
a fireman turns on
a hose and is
knocked
backwards. #21
a newtons first law
b newtons second law
c newtons third law

Explanation:

Newton's Third Law states that for every action, there is an equal and opposite reaction. When the fireman turns on the hose, the water rushing out (action) exerts a force on the fireman (reaction), knocking him backwards. This is a classic example of action - reaction pairs. Newton's First Law is about an object's state of motion (at rest or in uniform motion) unless acted on by a net external force. Newton's Second Law is about the relationship between force, mass, and acceleration ($F = ma$).

Answer:

c. Newton's Third Law
