That depends on what is it made of, however even lead cannon ball would float in Mercury, let alone steel one. If you compare densities, you can see that mercury is more dense than lead in room temperature (13530 kg m-3 vs 11 540 kg m-3).
One can imagine a cannon ball made of depleted uranium perhaps, which would sink in mercury, being more dense.

I dug a cannonball out of the ground ...im wondering what it is worth ?

The cannon (also called artillery or gun or field piece) has no acceleration. It's just a stationary tube; a gun barrel.The cannon ball (also called a shell or projectile) travels at a speed determined by it's propellent charge; interior of the gun tube (rifled or smoothbore); length of gun tube; and the caliber of the weapon (gun size).As a rule: Larger projectiles travel slower; rifled barrels shoot slower projectiles; shorter gun tube have shorter ranges; smaller powder charges (propellent) travel smaller distances.I'm sorry, but the cannon does accelerate in the opposite direction of the cannon ball. This is called recoil. Old cannons simply rolled backwards as a result of recoil and had to be manually pulled forward again and reaimed. Modern artillery pieces all use recoil absorbing mechanisms that permit the barrel to recoil without moving the carriage, then automatically reextend the barrel.To answer the original question, the cannon is heavier and the ball is lighter, therefor the ball accelerates faster than the cannon.
With both projectiles round and made of the same heavy material (same densities), they'd get to the ground at the same time. Air resistance would be minimized this way. A ping pong ball cannot fall as fast as a cannon ball unless both are falling in a vacuum. Galileo put us straight on this phenomenon.
No, a steel ball will not float in mercury, even if it is heated. Mercury is much denser than steel, so the steel ball will sink in mercury regardless of its temperature.
An iron ball floats on mercury because mercury is much denser than iron. The buoyant force acting on the iron ball due to the displacement of mercury is greater than the gravitational force pulling it downward, causing it to float.
Depends on the medium, and whether the ball is solid or not. A solid ball would float on mercury, sink in water. If it were hollow enough (or filled with, say, cork) it would float in water.

Yes, nickel can float on liquid mercury because the density of nickel is lower than that of mercury. This means that nickel will not sink when placed on liquid mercury, and instead will float on its surface.
it will float
No, mercury is denser than ethanol, so it will sink and not float.

the size of the cannon ball depends on the size of the cannon. civil war cannons had cannon balls about the size of a child's head, aprox 30cm across

Yes, wood will float on mercury because mercury is much denser than wood. The density of mercury is about 13.6 times greater than that of wood, so wood will not sink in mercury and will actually float on its surface.
Solid iron will float in liquid mercury. In most liquids it will sink.
