 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Newton’s third law states:for every action, there is an equal and opposite reaction. Explain why, then, a cannon does not go as far as backward as a cannonball goes forward.
 A The cannonball has less mass, and mass and acceleration are inversely proportional B The cannon has less mass, and mass and acceleration are inversely proportional C The cannonball has less mass, and mass and acceleration are directly proportional D Newton’s third law does not always apply
Explanation:

Detailed explanation-1: -Newton’s third law states that for every action there must be an equal and opposite reaction, so the forces on the cannon and cannonball are equal in magnitude (but not direction). and the mass of the cannon is larger than the mass of the cannonball, so the acceleration is lesser for the cannon than for the cannonball.

Detailed explanation-2: -According to Newton’s third law of motion, forces always act in equal but opposite pairs. Another way of saying this is for every action, there is an equal but opposite reaction. This means that when you push on a wall, the wall pushes back on you with a force equal in strength to the force you exerted.

Detailed explanation-3: -Newton’s Third Law is that of Action-Reaction which states that for every action there is an equal and opposite reaction. This means that as you are pushed down, further and further in your seat, the seat is pushing back at you.
