A 25 kg cannon ball is shot out of a 1600 kg cannon that is initially at rest. When fired, the velocity of the cannon ball is 200 m/s. What is the recoil velocity of the cannon?​

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
