Answer:
The angular displacement is 37.5 radian.
Explanation:
Given that,
The radius of the car, r = 0.3 m
The acceleration of the car, [tex]\alpha =3\ rad/s^2[/tex]
The initial speed of the car, [tex]\omega_i=0[/tex]
Time, t = 5 s
The angular displacement can be calculated using second equation of motion i.e.
[tex]\theta=\omega_it+\dfrac{1}{2}\alpha t^2\\\\\theta=\dfrac{1}{2}\alpha t^2\\\\\theta=\dfrac{1}{2}\times 3\times (5)^2\\\\\theta=37.5\ rad[/tex]
So, it will make 37.5 radians.
