To find acceleration you subtract the final velocity and subtract it from the initial velocity and you divide the difference by the total time.

so you take the final velocity which is 0 m/s because the car comes to a complete stop.

then you subtract that from the initial which is 26 m/s

in other words:

0m/s - 26 m/s = - 26 m/s

then you divide it by the total time which is 13 s

-26 m/s / 13 s

so you get

-2 m/s^2
