A trough is 7 meters long, 2.5 meters wide, and 3 meters deep. The vertical cross-section of the trough parallel to an end is shaped like an isoceles triangle (with height 3 meters, and base, on top, of length 2.5 meters). The trough is full of water (density 1000kg/m3). Find the amount of work in joules required to empty the trough by pumping the water over the top. (Note: Use g = 9.8m/s2 as the acceleration due to gravity.) Show transcribed image text
