Bullets obviously start at rest.So,how much time does it take to reach maximum velocity.

A bullet will hit maximum velocity as it is fired, from this point on it slows down due to air resistance etc.
Interstingly the barrel of the gun spins the bullets as they travel down the barrel, this is supposed to make the bullet more accurate and fly further.

Several things affect the velocity of a bullet.
The propellant,gun powder[slow] cordite [fast]
The length of the barrel 2 inches or one foot.
The bullet accelerates through the barrel so the expansion speed of the gasses and the length of the acceleration path,would determine the length of time the reach maximum speed. Maybe one three thousands of a second.
C4 expands at about 8000 ft per second it would probably destroy the barrel of a gun.

A shell from the Paris Gun reached a velocity of 5,2 hundred feet/s. That change into using uncomplicated gun powder propellant. The M829A2 APFSDS around the M1A1 Abrams fires from this is 120mm important gun is somewhat faster. Then there change into challenge HARP. A non-rocket area launch approach in accordance with an exceedingly tremendous gun to fireside the fashions to extreme altitudes and speeds (aka an area gun). If I were given my math top they fired a shell at 11,810 fps. As for small hands i do no longer understand. i will anticipate the reduce will be depending on the propellant used.

The propulsive power of the gun powder and the barrel of the gun cause the rapidly expanding gasses to propel the projectile forward. this obeys newtons first law for every action there is an equal but opposite reaction. Because the gas expands in all directions it exerts a force on the gun and the bullet equally the bullet moves because the force acting on it is greater than the force needed to move the bullet. the gun doesn't move as much because the force required to move it is greater.

Typically bullets fired from pistols and revolvers travel at 300 - 500 m/s.
Hunting or miltary bullets are faster (approx. 800 - 1000 m/s).
Air rifles are in the 100 - 200 m/s range.

at the firing point, they start losing it once out of the barrel.
