Here's how to solve this problem using the following equation of motion:

v = u + at

where:

* v is the final velocity

* u is the initial velocity (24 m/s)

* a is the acceleration (2 m/s²)

* t is the time (8 s)

Let's plug in the values:

v = 24 m/s + (2 m/s² * 8 s)

v = 24 m/s + 16 m/s

v = 40 m/s

Therefore, the final velocity of the car is 40 m/s.
