Fundamental Problem 15.12
The cannon and support without a projectile have a mass of 250 kg. If a 20 kg projectile is fired from the cannon with a velocity of 400 m/s , measured relative to the cannon, determine the speed of the projectile as it leaves the barrel of the cannon. Neglect rolling resistance.
