1990 feet per second.
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
There have been more than 2 dozen DIFFERENT 20mm cannon (search 20mm Wikipedia for examples). These used different shells, and had different barrel lengths, and so have different muzzle velocities. The 20mm used by the US and Allies during WW II had a muzzle velocity of ABOUT 2800 feet 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.
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.
No.
I assume it is a 45/70 trapdoor carbine. go to: trapdoors.com and compare your gun to those being sold, and their price

$75 to $400 US depending on the condition.
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.
Average velocity is total distance by total time . let us calculate velocity at the end of 6 seconds. v=vo+at v= 0+1.7*6 v=10.2 m/sec distance travelled by object in six seconds x= vot+1/2at2 x=0+.5(1.7)(62) x=30.6 m the final velocity at the end of six seconds that is 10.2m/s will be the initial velocity when objects moves with uniform velocity with a constant velocity x= vot+1/2at2 . . . accel is 0 since velocity is constant between 6 & 15 secs. x=10.2*9=91.8 Again . . average velocity is total distance by total time. Average velocity= [30.6+91.8]/15= 122.4*15 = 8.16m/s
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.
