$2)$ The retaining wall shown below needs to be designed for two loading conditions: one static loading condition with an impact load and one loading condition for seismic without the impact load. The loading conditions are shown below.

The retaining wall is attached to the concrete footing with rebar dowels $($meaning there will be no sliding of wall on footing and the only place the footing can slide is the contact between the bottom of the footing and soil$).$ The upper wall weight is $450$ lb given a coefficient of static friction of $0\mathrm{.}3$ for the surface between the bottom of the footing and the soil. Is the design of the wall footing adequate to not slide away? If the current footing design is not adequate, what is the minimum footing weight needed for the wall to not slide away? Assume the ground is a solid surface. $(50$ pts $)$
