Answer:
H. The ball pushing on the bat
Step-by-step explanation:
The question above is related to "Newton's Third Law of Motion." This law states that if an object exerts a force on another object, the second object will exert the same amount of force on the first object but in an "opposite direction." The force exerted by the first object is known as "action force" while the force exerted by the second object is known as "reaction force."
In the situation above, the ball is exerting an "action force on the bat" by pushing the bat. The bat then reacts to its force by pushing it back with an equal force (reaction force) that is opposing it.
