Given data
The angular acceleration of the car is
[tex]\alpha=6.8rad/s^2[/tex]The given time is t = 25 s
The expression for the angular displacement is given by the rotational equation of motion as
[tex]\theta=\frac{1}{2}\alpha t^2[/tex]Substitute the values in the above expression as
[tex]\begin{gathered} \theta=\frac{1}{2}(6.8)(25)^2 \\ =2125\text{ rad} \end{gathered}[/tex]
