Work 0f3 Joules is done in stretching a spring mm its natural length to 17 cm beyond its natural length. What is the force (in Newtons) that holds the spring stretched at the same distance (17 cm)?| I A circular swimming pool has a diameter of 12 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/32 and the density of water is 1000 kg/m3.) How much work (in Joules) is required to: (a) pump all of the water over the side? I I (b) pump all of the water out of an outlet 2 m over the side? I I A tank in the shape of an inverted right circular cone has height 8 meters and radius 7 meters. It is filled with 4 meters of hot chocolate. Find the work required to empty the tank by pumping the hot chocolate over the top of the tank. Note: the density of hot chocolate is 6 = 1520kg/m3
