Answer:
Acceleration of the car, [tex]a=9.87\ m/s^2[/tex]
Explanation:
Initial sped of the car, u = 0
Distance covered by the car, d = 100 m
Time taken, t = 4.5 s
Let a is the acceleration of the car. It can be calculated using second equation of kinematics as :
[tex]d=ut+\dfrac{1}{2}at^2[/tex]
[tex]d=\dfrac{1}{2}at^2[/tex]
[tex]a=\dfrac{2d}{t^2}[/tex]
[tex]a=\dfrac{2\times 100}{(4.5)^2}[/tex]
[tex]a=9.87\ m/s^2[/tex]
So, the acceleration of the car is [tex]9.87\ m/s^2[/tex]. Hence, this is the required solution.
