A batsman hits a ball with a force a 7 N. What force does the bat experience?

According to Newton's third law, when two bodies interact, they apply forces to each other that are equal in magnitude and opposing in direction. The third law is also known as the action-reaction law.

From Newton’s third law we know that for every for every action, there is an equal and opposite reaction. From this we can say that the bat experiences a force of 7 N.
