A rectangular tank containing water is open at the top and has a width of 3 m and a depth of 2.5 m. It accelerates horizontally in the direction of its length at a constant rate of 4.5 m/s2. If the tank is completely full before acceleration, calculate the total hydrostatic force acting on the higher pressure end (rear wall) due to water (assume g = 9.81 m/s2 and density of water = 1000 kg/m3).
