For Problems $13\mathrm{.}10$ to $13\mathrm{.}13,$ if Rankine's coefficient $k_a$ is $0\mathrm{.}75,$ the soil weighs $110l\frac{b}{f}{t}^3,$ the concrete weighs $150l\frac{b}{f}{t}^3,$ and the ceefficient of friction $($concrete on soil$)$ is $0\mathrm{.}55,$ determine the safety factors against overturning and sliding for the wall shown.
