Well moron, if the USA could fire a ICBM at Red Square and hit the trash can in the North -West corner of the plaza way back in the early eighties I think that by now we could even hit your minisule brain and help you sleep bettter since we have had twenty plus more years to improve to hit something that small !!!

You can sleep just fine tonight. The cannonball burned up on it's trajectory to reach the speed needed to orbit the earth. But, then on the other hand, I'm a little concerned about how close you are to the cannon that could fire a cannonball with that much force. If you survived the blast, be sure to wear good earplugs.

Yes. The escape velocity of Earth is roughly 7miles/sec. If a projectile is shot at this velocity it is likely to escape Earth's gravity. This value does not include the component to cater for air resistance. The correct height, angle,and velocity and the time of launch, [called Launch Window] form the subject matter of Space Science and Technology. Other factors to consider what kind of orbit? Geo-synchronous or otherwise. We need to take of all these factors for a successful launch so it goes round Earth and not come back and hit you on your head!

You have to get the right speed in there too, right angle, right velocity and trajectory and the cannon ball will hit you in the back of the head, but you wouldn't be able to sleep, the cannon ball would turn your head into a reddish pink gooey mess that no one would be able to recognize. As a matter of fact it would just take your head off.

if you calculate the speed proportionate with the amount of friction it will recieve while roating around the earth and also the amount of gravataional pull that will inteact with the cannonball then you technically could

That is exactly correct, neglecting drag from the air of course. Air drag is the only reason you have to be above the atmosphere to stay in orbit.
