Work is the integral of the fores (over distance — see Eg. 7-32). and referring to the equation immediately preceding Eq. 14-7. we see the work can be written as W= [picas EA(3) dy where we are using y = O to refer to the water surface (and the +y direction is upward). Let h=0.500 m. Then. the integral has a lower limit of —h and an upper limit of. with Xg/h = — Peytinder /Pwater =— 0.400. The integral leads to W=1 puamgAh(1 0.47) = 411 kT.
