A cannonball weighing 9 kg flies out of the barrel at a speed of 800 m / s. The cannon barrel travels in 0.008 s. Find the average force of the pressure of the powder gases.
Data: m (mass of the cannonball) = 9 kg; V (velocity of departure of the considered nucleus from the trunk) = 800 m / s; t (the duration of the passage of the cannon barrel by the cannon) = 0.008 s.
To find the average force of the pressure of the powder gases on the core, we will use the equality: F * t = m * V and F = m * V / t.
Calculation: F = 9 * 800 / 0.008 = 900 * 103 N (900 kN).
Answer: The required average force of pressure of powder gases on the core is 900 kN.
