Got it. Thanks. Now the one that you said that something were missing you are right. Here is the correction:

22. Consider a volume V of gas in a cylinder fitted with a piston at one end, where the pressure p of the gas is a function p(V) of its volume (Fig 6.5.17). Let A be the Area of the face of the piston. Then the force exerted on the piston by gas in the cylinder is F = pA. Assume that the gas expands from volume V_1 to volume V_2 is then given by: (You have the rest)

8. y = x^2, y = 9

I made an error on #8. I was only looking at the region in the 1st quadrant. The correct answer for x bar is 0 (by symmetry). y bar is correct.

Sorry.
