    Answer: 113.75

    Explanation:

    You know

    acceleration = a = 3.5 m/s²

    time = t = 5 seconds

    initial velocity = u = 14 m/s

    Unknown is distance = s = ?

    Use equation: s = ut + \frac{1}{2} at²

    Substitute all the known values inside the equation:

    s = (14*5) + 0.5 * 3.5 * 5²

    s = 70 + 43.75 = 113.75 m

    The car travels 113.75 metres.
