Answer:

the acceleration of the racecar is 6.5 m/s²

Explanation:

Given;

initial velocity of the racecar, u = 0

final velocity of the racecar, v = 39 m/s

time of motion, t = 6.0 s

The acceleration of the racecar is calculated as;

[tex]a = \frac{v-u}{t} \\\\a = \frac{39-0}{6} \\\\a = \frac{39}{6} \\\\a = 6.5 \ m/s^2[/tex]

Therefore, the acceleration of the racecar is 6.5 m/s²
