A trough is 10 feet long and 1 foot high. The vertical cross-section of the trough parallel to an end is shaped like the graph of y = a from z = -1 to x = 1 . The trough is full of water. Find the amount of work in foot-pounds required to empty the trough by pumping the water over the top. Note: The weight of water is 62 pounds per cubic foot. A tank in the shape of an inverted right circular cone has height 6 meters and radius 2 meters. It is filled with 3 meters of hot chocolate. Find the work required to empty the tank by pumping the hot chocolate over the top of the tank. The density of hot chocolate is o = 1100 kg/m . Your answer must include the correct units Work = circular swimming pool has a diameter of 12 m. The circular side of the pool is 4 m high, and the depth of the water is 2.5 m. (The acceleration due to gravity is 9.8 m/ s d the density of water is 1000 kg/m3) ow much work (in Joules) is required to: pump all of the water over the side? pump all of the water out of an outlet 3 m over the side
