# A projectile with a mass of 10 kg flew out of the gun at a speed of 600 m / s. Determine the average pressure

A projectile with a mass of 10 kg flew out of the gun at a speed of 600 m / s. Determine the average pressure of the powder gases if the projectile moves inside the barrel of the gun 0.005 s

Projectile acceleration can be found by dividing the velocity increment by the time over which this increment occurred:

a = Δv / Δt = 600 m / s / 0.005 s = 120,000 m / s2.

Acceleration is directly proportional to the acting force and inversely proportional to mass:

a = F / m.

Force acting on the projectile:

F = ma = 10 kg * 120,000 m / s2 = 1.2 * 10 ^ 6 N.

Answer: 1.2 * 10 ^ 6 N.
