initial velocity of the car given as

[tex]v_i = 0[/tex]

final velocity is given as

[tex]v_f = 108 km/h[/tex]

as we know that

[tex]1 km/h = 0.277 m/s[/tex]

now we can convert final speed into m/s

[tex]v_f = 108 * 0.277 = 30 m/s[/tex]

now acceleration is rate of change in velocity

[tex]a = \frac{v_f - v_i}{t}[/tex]

[tex]a = \frac{30 - 0}{10}[/tex]

[tex]a = 3 m/s^2[/tex]

so the acceleration of the car is 3 m/s^2
