$.$ A box with mass m is sliding up a ramp that is inclined at $36\mathrm{.}9$ above the horizontal. If the coefficient of kinetic friction between the box and the surface of the ramp is u$=0\mathrm{.}300,$ what is the magnitude of the acceleration of the box as it moves up the ramp?

$($a$)2\mathrm{.}4$ m$/$s$^2$

$($b$)3\mathrm{.}5$ m$/$s$^2$

$($c$)5\mathrm{.}9$ m$/$s$^2$

$($d$)8\mathrm{.}2$ m$/$s$^2$

$($e$)9\mathrm{.}8$ m$/$s$^2$

m

$36\mathrm{.}9$

$($f$)$ none of the above answers
