**[SOLVED] Hydrostatic Forces**

Any Help would be GREATLY appreciated. My grade depends on me understanding this.

## Homework Statement

A tank contains freshwater. The end of a tank containing water is vertical and has the indicated shape. Explain how to approximate the hydrostatic force against the end of the tank by a Riemann sum. Then express the force as an integral and evaluate it.

## Homework Equations

F=pgAd

A=wdx

## The Attempt at a Solution

F= int 0->5 1000(9.8)2sqrt(100-y^2)(5)

98000*int 0->5 sqrt(100-y^2)

u=100-y^2

-1/2*du=dy

98000*int 75->100 u^(.5)

98000{(2/3)u^(3/2)} 75->100
