A trough is 5 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 1000- kg ). Find the amount of work in joules required to m3 empty the trough by pumping the water over the top. (Note: Use g = 9.8. gravity.) m as the acceleration due to 82 5m 2.5m 3m A trough is 5 meters long, 2.5 meters wide, and 3 meters deep.
