[填空题]
On mountainous downhill roads, escape routes muiz1mw(f b)* are sometimes placed to the suhmy:0 4 d7xyot*p1r qide of the rd1o4yx*urpq m:t 0y 7hoad for trucks whose brakes might fail. Assuming a constant upward slope of 32$^{\circ}$ , calculate the horizontal and vertical components of the acceleration of a truck that slowed from 120 $\mathrm{~km} / \mathrm{h}$ to rest in 6.0 s . See Fig. below
$\text { The horizontal acceleration is } a_{\text {hoiz }}$ = $\mathrm{m} / \mathrm{s}^{2}$
$\text { The vertical acceleration is } a_{\text {vert }}$ = $\mathrm{m} / \mathrm{s}^{2}$
