Aplayer hit a serve in a racket sport that was clocked at 59 mph. how much work did she have to do on the 8-oz ball to get it to that speed? w = ft-lb

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
