Answer:
See explanation below
Explanation:
A) The force that the cannon exerts on the cannonball is the same as the force the cannonball exerts on the cannon because of Newton's Third Law stating "for every action, there's an equal and opposite reaction".
B) The cannon's acceleration is much smaller than that of the cannonball because the cannon has a much larger mass, making it have a very small acceleration since mass and acceleration are inversely proportional.
