The Deligne Dam on the Cayley River is built so that the wall facing the water is shaped like the region above the curve y = 0.7z and below the line y = 140, (Here, distances are measured in meters.) The water level is 28 meters below k the top of the dam. Find the force (in Newtons) exerted on the dam by water pressure. (Water has a density of ll}[}[}gg, m m and the acceleration of gravity is 9.82 J sec
