A circular swimming pool has a diameter of 14 m. The circular side of the pool is 3 m high, and the depth of the water is 2.5 m. (The acceleration due to gravity is 9.8 m/s2 and the density of water is 1000 leg/177,3.) How much work (in Joules) is required to: (a) pump all of the water over the side? D (b) pump all of the water out of an outlet 3 m over the side? 8
