(vf-vi) ÷ t = a

(40-0) ÷ 5 = 8m/s²

Answer:

Acceleration, [tex]a=8\ m/s^2[/tex]

Explanation:

Given that,

Initial velocity of the car, u = 0

Final velocity of the car, v = 40 m/s

Time taken, t = 5 s

Let a is the acceleration of the car. It can be calculated using first equation of motion as :

v = u + at

v = at

40 = a × 5

[tex]a=8\ m/s^2[/tex]

So, the acceleration of the car is [tex]8\ m/s^2[/tex]. Hence, this is the required solution.
