What is the acceleration of a spaceship that is initially at rest and then speeds up to 220 m/s in 20 seconds

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

Specific heat refers to the amount of heat required to change 1 gram of a substance by degree(s) celsius
