Bullets fired from a gun don't accelerate, the decelerate from the moment they leave the barrel.
When a bullet is fired out of a gun, the bullet's acceleration and the gun's acceleration are equal in magnitude by opposite in direction. This is the cause of kickback from the gun. The reason why the gun doesn't rip your arm off though is because it's sheer size or mass, resulting in a much smaller impact on the object it collides with.
The moon has no atmosphere and has less gravity than the earth. That means that a cannonball fired on the moon will travel further.

he was hired and fired on the same day
throught the use of pressure/fire/gun powder
We calculated the trajectory of the cannonball before we fired it.
He got fired! ha! ha! ha!
The bullet fired from a gun has greater horizontal acceleration. For vertical acceleration, they are both the same.
It will awaken the bird.
"For every action, there is an equal and oposite reaction." The cannonball is pushed out of the barrel at high speed. This pushes the cannon in the opposite direction. That is recoil. The heavier the cannonball, and the faster it is pushed, the more the cannon recoils.
Yes, and the classic example that all mathematics students study is the motion of a projectile. Typically a ball is thrown (or a cannonball fired) at an angle to the horizon and pupils study its trajectory. With some simplifying assumptions, the trajectory is a parabola. Ignoring air resistance (a simplifying assumption), the only acceleration is due to the downward acting force of gravity.
