    Answer: time is 47.56sec

    Explanation: acceleration is define as the rate of change of velocity. That is,

    Acceleration = velocity/time

    Since we’re told to find the time we can make time t the subject of formula in the above equation.

    So we have,

    Time = Velocity/Acceleration

    But from the question velocity is given as 16.98 m/s while acceleration is given as 0.357m/s²

    So we have,

    Time = 16.98/0.357 = 47.56seconds
