Answer:

Explanation:

As the car Started from rest means that Initial Velocity "Vi = 0 m/s" and final Velocity is given "Vf = 42m/s". Time is given "t = 6.2s"

Acceleration is required a =?

Use Formula;;    a = [tex]\frac{Vf-Vi}{t}[/tex]

a = [tex]\frac{42-0}{6.2}[/tex]

a = 6.7741 m/s² ≈ 6.8 m/s²
