(1 point) A trough is 7 meters long, 1.5 meters wide, and 1 meters deep. The vertical cross-section of the trough parallel to an end is shaped like an isoceles triangle (with height 1 meters, and base, on top, of length 1.5 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 9.8mls2 as the acceleration due to gravity.) Joules
