Answer:
[tex]14m/s^2[/tex]
Explanation:
Initial speed of car=0 Km/h=[tex]0m/s[/tex]
Final speed of car=[tex]100km/h=100\times \frac{5}{18}=\frac{250}{9} m/s[/tex]
By using [tex]1km/h=\frac{5}{18}m/s[/tex]
Time taken by car=2 s
We know that
Acceleration=[tex]a=\frac{v-u}{t}[/tex]
Where v=Final velocity of object
u=Initial velocity of object
t=Time taken by object
Using the formula
Acceleration of car=[tex]\frac{\frac{250}{9}-0}{2}=\frac{250}{9\times 2}=13.9 m/s^2\approx 14m/s^2[/tex]
Hence, the acceleration of car about=[tex]14m/s^2[/tex]
