Question

how does this photograph illustrate newtons third law of motion? a the greater the swimmers acceleration, the more force applied and the lower his mass. b the more force the swimmer applies back on the wall, the faster his movement forward in the water. c in order for the swimmer to move forward in the water there must be an unbalanced force acting on the swimmer. d the force acting forward is greater than the force acting in the opposite direction: the swimmer accelerates.

Explanation:

Newton's third - law states that for every action, there is an equal and opposite reaction. When the swimmer pushes back on the wall (action force), the wall exerts an equal and opposite reaction force that propels the swimmer forward. The more force the swimmer applies to the wall, the greater the reaction force and the faster the swimmer moves forward.

Answer:

B. The more force the swimmer applies back on the wall, the faster his movement forward in the water.
