Part A

Determine the minimum force $\backslash ($ P $\backslash )$ required to push the crate up the plane. The crate has a mass of $28$ kg and the coefficient of static friction between the crate and the plane is $\backslash (\backslash$mu$\_\{\backslash$mathrm$\{$s$\}\}=0\mathrm{.}40\backslash ).($Figure $1)$ Express your answer with the appropriate units.
