Let $+$x be in the horizontal direction and positive to the right.$$ A $38\mathrm{.}9$ N pushing force is acting on a $4\mathrm{.}02$ kg block across a floor at a direction of $15\mathrm{.}5$ degrees above the $+$x axis. There is a frictional$$ force present and the coefficient of friction between the block and the floor is $0\mathrm{.}25.$ What is the horizontal acceleration of the block $($in m$/$s$2)?$
