    The acceleration of car is 0.2 ms⁻²

    Explanation:

    When the car moves , the distance covered is calculated by the relation

    S = u t + \frac{1}{2} a t²

    In this question u = 0 , because car was at rest initially

    Thus S =  \frac{1}{2} a t²

    here S is displacement and a is the acceleration of car

    Therefore  360 =  \frac{1}{2} a ( 60 )²

    Because time taken is one minute or 60 seconds

    Therefore a = \frac{360x2}{3600}

    or a = 0.2 m s⁻²
