Two trucks A and B are approaching each other on a straight path with the velocities of $\displaystyle 16 \mathrm{~m} / \mathrm{s}$ and $\displaystyle 20 \mathrm{~m} / \mathrm{s}$ respectively. When they are $\displaystyle 200$ m apart their drivers see each other and applies the breaks simultaneously. If the truck A decelerates with $\displaystyle 2 \mathrm{~m} / \mathrm{s}^2$ and truck $\displaystyle B$ decelerates with $\displaystyle 4 \mathrm{~m} / \mathrm{s}^2$, what is the distance between them when they finally stop?
