    Average acceleration is 6.49 m/s²

    Explanation:

    We have equation of motion v = u + at

    Initial velocity, u = 0 m/s

    Final velocity, v = 22.2 m/s

    Time, t = 3.42 s

    Substituting

    v = u + at

    22.2 = 0 + a x 3.42

    a = 6.49 m/s²

    Acceleration is 6.49 m/s²

    Average acceleration is 6.49 m/s²
