Firing

1. Cannon construction design choice
We choose to use are second ball holder as an base to provide stability for the cannon.We put the cannon at a 47degrees angle because if it was fifty or more it would shoot up right. If it was 40 or less it would hit the ground right after it left the cannon.

2.Launch angle choice
47degrees

3.Expected results.
That is would go very very far.

4. Difficulties in construction(What would you do differently?)
The first problem that faced was trying construct the right while trying to conserve our tape supply since we were limited to 18 inches.

5. Record the distance your cannon shot the Nerf ball(in Feet)
0ft.

6. Determine the initial velocity of the firing. Show the equation and work for the velocity calculations.
0 velocity

Cannons from modern day

Cannon also transformed naval warfare: the Royal Navy, in particular, took advantage of their firepower. As rifling became more commonplace, the accuracy of cannon was significantly improved, and they became deadlier than ever, especially to infantry. In World War I, the majority of all deaths were caused by cannon; they were also used widely in World War II. Most modern cannon are similar to those used in the Second World War, except for heavy naval guns, which have been replaced by missiles. In particular, autocannon have remained nearly identical to their World War II counterparts.

Cannons in the 1800's

Up until the early 1800's cannon were fired by putting a little powder in the touch hole at the breech end of the gun, then applying a burning wick of slow match to the powder, sending a spark down the touch hole and igniting the powder cartridge. In the early 1800s a version of the flintlock mechanism being used on muskets was adapted to fit cannon, allowing the gun to be fired by simply pulling a lanyard.

Cannon's Before The 1700's

-Houchong cannon dating back to the Chinese Song Dynasty

The history of cannons spans over serval hundred years, Ctesibius of Alexandria invented the earliest known cannon in the third century but his work were lost in history. The Philo of Byzantium noted that his primitive invention used a form of compressed air to operate.The Chinese were the first to use gunpowder artillery in the early 1100's. The first documented battle using houchongs was in January 28, 1132. Song General Han Shizhong used them to capture a Fuijian city. The first houchongs were constructed out of bamboo but later the bamboo was replaced with bronze in the 13th and 14th centurys. This early form of gunpowder artillary weapon is known by many as the first cannon dating back to 1298.
