A projectile weighing 15 kg, when fired, acquires a speed of 600 m / s.

A projectile weighing 15 kg, when fired, acquires a speed of 600 m / s. Find the average force with which the propellant gases press on the projectile if the barrel length is 1.8 m. The movement of the projectile is uniform.

Task data: m (projectile mass) = 15 kg; V (the speed that the projectile acquired) = 600 m / s; L (length of the gun barrel, distance traveled by the projectile) = 1.8 m; V0 (initial velocity of the projectile) = 0 m / s.

The average force with which the propellant gases act on the projectile is determined by the formula: F = m * a = m * (V2 / 2S).

Calculation: F = 15 * 6002 / (2 * 1.8) = 1,500,000 N (1.5 MN).

Answer: Powder gases act on the projectile with an average force of 1.5 MN.
