$4.$ Traction$-$Limited Acceleration Analysis $($Longitudinal Load Transfer$).$ Consider a $2900-$

$\backslash (\backslash$rightarrow $\backslash$mathrm$\{$lb$\}\backslash )$ front$-$wheel drive van undergoing friction$-$limited acceleration $($likely the case at low speeds, for which the power$-$limited acceleration is quite high$)$ on a rainy asphalt with a coefficient of $0\mathrm{.}3.$ The CG is $\backslash ($ h$=2\mathrm{.}5\backslash$mathrm$\{$ft$\}\backslash )$ above the roadway, and falls $\backslash ($ b$=4\backslash$mathrm$\{$ft$\}\backslash )$ aft of the front axle; the wheelbase is $\backslash ($ L$=10\backslash$mathrm$\{$ft$\}\backslash ).$ Considering longitudinal load transfer, estimate the maximum acceleration possible.
