Newton's Laws of motion describe the motion of an object based on the applied force
The correct option that gives the relationships between the forces is the the option;
<u> on bat</u> =
<u> on ball</u>
<em>(Either option A or B without the minus symbol before </em><em>, likely typographical error)</em>
<em />
Reason:
Force exerted on the bat by the ball =
Force exerted on the ball by the bat =
Given that the batter hits the ball with the bat, the force exerted by the bat on the ball, , is reacted to by the force of the ball acting on the bat,
According to Newton's third law of motion, action and reaction are equal and opposite. Therefore, at the moment when the ball hits the bat, we have;
<u> on bat</u> =
<u> on ball</u>
<em>Where the force of the bat is high, the ball is accelerated to travel at high speed</em>

<h2>Hello!</h2>
The answer is: B. Kinetic energy
<h2>Why?</h2>Since the ball is falling, speed increases because the gravity acceleration is acting. When speed increases, the kinetic energy increases too, so the ball is gaining kinetic energy.
The gravity acceleration is equal to , it means that when falling, the ball will increase it's speed 9.81m every second.
We can calculate the kinetic energy by using the following formula:
