Question

as clinton walks he pushes his shoe against the track.
which of the following best describes the reaction force to clinton’s shoe pushing against the track?
a. the track pushes against gravity with the same force.
b. the track pushes back on clinton’s shoe with the same force.
c. the track pushes in a different direction with a different force.
d. the track pushes in the same direction as clinton’s shoe with the same force.

Explanation:

This is based on Newton's Third Law of Motion, which states that for every action force, there is an equal and opposite reaction force. Here, the action is the shoe pushing on the track, so the reaction is the track pushing back on the shoe with equal force in the opposite direction.

Answer:

B. The track pushes back on Clinton's shoe with the same force.
