Consider a swimming pool of width 4m and length 12m that is filled with water to a depth of 5 m. a) Calculate pressure (in Pa) half way down the pool due to the water assuming the density of watter is 1.000 kg/m3 and take into account the air above the pool. Remember to use 9.8 m/s as the acceleration due to gravity b) What is the nel force on a ball of mass 5.9 kg and volume of 0.2 m^3 when the submerged under water? g= 9.8m/s^2, density = 1000 kg/m^3
