$14\mathrm{.}1$ through $14\mathrm{.}4$ Figure $14\mathrm{.}35$ shows a retaining wall that is restrained from yielding. For each problem, determine the magnitude of the lateral earth force per unit length of the wall. Also, find the location of the resultant, $\frac{?}{\text{b}\text{a}\text{r}}(z),$ measured from the bottom of the wall.
