A revolutionary war cannon, with a mass of 2220 kg, fires a 22.7 kg ball horizontally. The cannonball has a speed of 126 m/s speed of the cannon immediately after it was fired? = 1.28 m/s. The same explosive charge is used, so the
total energy of the cannon plus cannonball system remains the same. Disregarding friction, how much faster would the ball travel if the cannon were mounted rigidly and all other parameters remained the same?
