When a car moves from rest then the initial velocity,
[tex]u = 0m {s}^{ - 1} [/tex]
The final velocity,
[tex]v = 25m {s}^{ - 1} [/tex]
and time,
[tex]t = 30s[/tex]
Using the equation,
[tex]v = u + at[/tex]
We have,
[tex]25 = 0 + a(30)[/tex]
[tex]25 = 30a[/tex]
[tex] \frac{25}{30} = a[/tex]
[tex] \therefore \: a = \frac{5}{6} m {s}^{ - 2} [/tex]
