which situation is an example of newtons third law of motion which is about action reaction?
a a ball accelerates when kicked with a great amount of force.
c a person riding in a forward - moving car continues to move forward when the car stops suddenly.
b a ball slows down due to friction between the ball and grass.
d a person in a canoe moves the paddle backward in the water, and the canoe moves forward in the water.

Explanation:

Newton's third law states that for every action, there is an equal and opposite reaction. In option D, when the person moves the paddle backward (action), the water exerts an equal - and - opposite force on the canoe, making it move forward (reaction). Option A is an example of Newton's second law ($F = ma$), option B is related to friction, and option C is an example of Newton's first law (inertia).

Answer:

D. A person in a canoe moves the paddle backward in the water, and the canoe moves forward in the water.
