To find the pressure at the bottom of the tank, we can use the concept of hydrostatic pressure. Hydrostatic pressure is the pressure exerted by a fluid at rest due to the weight of the fluid above it.
We can determine the pressure at the bottom of the tank using the formula:
P = ρgh
Where P is the pressure, ρ is the density of the fluid, g is the acceleration due to gravity, and h is the height of the fluid column. In this case, the fluid is water and its density is approximately 1000 kg/m3. The acceleration due to gravity, g, is 9.8 m/s2.
Given that the tank falls vertically with an acceleration of 2 m/s2 and the depth of the water is 1.5 m, we need to consider the net acceleration acting on the water. The net acceleration is the sum of the acceleration due to gravity and the acceleration of the tank. In this case, the net acceleration is 9.8 m/s2 + 2 m/s2 = 11.8 m/s2.
Now, we can substitute the values into the formula:
P = 1000 kg/m3 * 11.8 m/s2 * 1.5 m
P = 17,700 N/m2
To convert the pressure from N/m2 to kN/m2, we divide by 1000:
P = 17,700 N/m2 / 1000 = 17.7 kN/m2
Therefore, the pressure at the bottom of the tank is 17.7 kN/m2.
