Aproton (mass m 1.67 x 1027 kg) is being accelerated along a straight line at 1.4 x 1015 m/s2 in a machine. the proton has an initial speed of 2.4 x 107 m/s and travels 3.0 cm
(a) what is its speed? 25195237.6452 m/s
(b) what is the increase in its kinetic energy? 16366 ×

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
