You can use $$x = x_{0} + v_{0}t - \frac{1}{2}kt²$$ where k is the magnitude of your deceleration constant. Of course, you will need to choose the time that's associated with such x endpoint. Instead, if you want to know where is the maximum x the particle will go after being decelerated until its speed goes to 0, you can use Torricelli's formula:  v^{...
