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 = 0.3 x 2 y=0.3x2 and below the line y = 120 y=120. (here, distances are measured in meters.) the water level is 30 30 meters below the top of the dam. find the force (in newtons) exerted on the dam by water pressure. (water has a density of 1000 kg m 3 1000kgm3, and the acceleration of gravity is 9.8 m sec 2 9.8msec2 .)
