A tank of water at rest is 2.0000 m deep.It is then accelerated at 5.0000 m/s²parallel to the original water surface,so that the front edge of the water in the tank is lowered to 1/2 its original value.What is the water pressure in the tank at the bottom back edge? A)29,430.0013 N/m² B)9 N/m² C)9810.00042 N/m² D)The length of the tank is needed.

The pressure at the bottom back edge is determined by the hydrostatic pressure due to the water depth and the additional pressure due to the acceleration. The effective depth is 2 m, and the acceleration adds to the gravitational force, resulting in a pressure of ρ(g+a)h = 1000 kg/m³ * (9.81 m/s² + 5 m/s²) * 2 m = 29,430 N/m².
