Answer
$x=82.0m$
Work Step by Step
When the car overtakes the truck, we know that they have travelled the same distance. Thus, we know:
$x_{car}=x_{truck}$
Thus, we find the following equation:
$\frac{1}{2}at^{2}=vt$
We plug in the known values to obtain:
$\frac{1}{2}(2.2m/s^{2})t^{2}=(9.5m/s)t$
$t=2\times\frac{(9.5m/s)}{(2.2m/s^{2})}=8.64s$
We now find:
$x=vt=(9.5m/s)(8.64s)=82.0m$
