A projectile weighing 10 kg flies out of the gun barrel at a speed of 600 m / s, knowing that the time of movement of the projectile inside the barrel is 0.008 s, determine the average pressure of the powder gases.

To find the value of the average pressure force of the powder gases on the specified projectile, we use the equality: Fпг * Δt = mc * V, from where we express: Fпг = mc * V / Δt.

Variables: mс – the mass of the specified projectile (mс = 10 kg); V – speed of departure from the trunk (V = 600 m / s); Δt is the duration of the movement of the specified projectile inside the barrel (Δt = 0.008 s).

Calculation: Fпг = mc * V / Δt = 10 * 600 / 0.008 = 750 * 103 N.

Answer: The average force of the pressure of the powder gases on the indicated projectile was 750 kN.
