Question

a) Let y denote the height in meters measured from the base of the dam. The hydrostatic force exerted by the water on the portion of the dam comprised between y m and y + ?y m is approximately p (y) ?y N. What is p (y)? Note that the density of water is ? = 1000 Kg / m³ and the acceleration due to gravity on the earth's surface is g = 9.8 m / s². Express your answer as a formula. Answer: b) In Newtons, what is the total hydrostatic force exerted on the dam? FORMATTING: If you round your answer, ensure that the round-off error is less than 1% of the value. Answer: Number

Step 1

8 \, \text{m/s}^2 \) The hydrostatic force formula is given by: \[ p(y) = \rho \cdot g \cdot (25 - y) \] Substitute the values: \[ p(y) = 1000 \times 9.8 \times (25 - y) \] \[ p(y) = 9800 \times (25 - y) \] \[ p(y) = 245000 - 9800y \] Therefore, the value of \( Show more…
