To solve the problem we will first start considering the Pressure given the hydrostatic definition of the product between the density, the gravity and the depth. We will define the area where the liquid acts and later we will use the definition of the force as a product between the pressure and the area to calculate the force given in the two depths. The gauge pressure at the depth x will be
This pressure acts on the strip of area
The force acting on that strip is given by,
To evaluate the force, we will then consider the integral of the pressure as a function of the Area, or the integral of the previously found terms.
Evaluating at the initial depth of 1.8m and the final depth of 4.4 we have then that,
Therefore the Net force will be
Answer:
∆ = 14°
Explanation:
Let the angle be ∆
Opposite = 2.07 m/s
Adjacent = 8.3 m/s
Tan ∆ = opposite / adjacent
Tan ∆ = 2.07 / 8.3
Tan ∆ = 0.2494
∆ = ArcTan (0.2494)
∆ = 14°
The angle from vertical the raindrops make for a person jogging is 14°
