Solution and answer:
Step 1: Recall the formula of acceleration.
[tex]a = \frac{v_{f} -v_{i}}{t}[/tex]
where Vf is the final velocity, Vi is the initial, t is the time, and a is the acceleration.
Step 2: Substitute the given terms.
[tex]a = \frac{(24m/s) -(0m/s)}{30s}[/tex]
Step 3: Find a.
[tex]a = \frac{24m/s}{30s}[/tex]
[tex]a = 0.8 m/s^{2}[/tex]
Therefore, we can conclude that the acceleartion of a car is at 0.8 m/s².
