Answer:

[tex]4 m/s^{2}[/tex]

Explanation:

Acceleration, [tex]a=\frac {v-u}{t}[/tex]

Where v and u are the final and initial velocities of the race car respectively, t is the time taken for the race car to attain velocity of 36 m/s.

Substituting 36 m/s for v, 28 m/s for u and 2 s for t then

[tex]a=\frac {36 m/s-28 m/s}{2}=4 m/s^{2}[/tex]
