Fps(feet per second) - used for muzzle velocity in the US mps (meters per second) - used for muzzle velocity outside of the US Jules - used for muzzle velocity RPM (rounds per minute) and BPS (bb's per second) or RPS (rounds per second) - rate of fire
The muzzle velocity of a 20 mm cannon can vary depending on the specific model and ammunition used. Generally, it can range from around 2,800 to 3,500 feet per second (853 to 1,067 meters per second).
The standard US infantry weapon was the Springfield muzzle loading percussion cap rifle fitted with a ring socket bayonet. Most of the artillery was also of the rifled muzzle loading variety. Cavalry troops used the breech loading Sharps Carbine, plus a sabre, and a percussion cap revolver. Officers also carried a revolver and a sabre in lieu of a rifle.
Could you define mk4? If you mean the M4 carbine, currently used by the US military, it is about 2900 fps. If you mean the .303 caliber #4Mk1 used by British forces in WW II, it is about 2441 fps.
No.
The average speed during that time is 20 km per hour. We can't say anything aboutthe velocity because you've told us nothing about the direction it traveled."Velocity" is NOT just a fancy word for 'speed'. It has a different meaning.
I assume it is a 45/70 trapdoor carbine. go to: trapdoors.com and compare your gun to those being sold, and their price
No Ammunition made in the US for the M-1 carbine was never corrosive, since the gas piston is NOT meant to be disassembled by the user- which corrosive ammo would require. Some Chinese ammo was made in M-1 carbine with fake headstamps that was VERY corrosive.

The only carbine that the US Army officially issued as standard issue was the US M-1 (or M-2 fully auto) Carbine. This was a WW2 and Korean War carbine. US Army marksmanship badges during the Vietnam War (M-14 & M-16 Rifles) were: Expert, Sharpshooter, and Marksman. The M-1 Garand Rifle is not to be confused with the M-1 Carbine. Both were general issue at the same time in both Korea and WW2; for the both the US Army and the US Marine Corps. The M-1 Rifle used a 30-06 cartridge and the M-1 Carbine used a cartridge about the size of a pistol/revolver .357 magnum cartridge. If a man has one of those "Carbine Expert 1st Class" badges, then it probably came from the Korean War/WW2 era; when those weapons were general issue.
The average velocity can be calculated as the total displacement of the object divided by the total time taken. The object's total displacement during the acceleration phase can be calculated using the equation for uniformly accelerated motion. For the remaining 9 seconds, the object travels at a constant velocity, so the average velocity will be the same as this constant velocity. Calculate the total displacement for the acceleration phase and divide by the total time (15 seconds) to find the average velocity.
