    6.64 m/s²

    Explanation:

    Given in the question,

    time it take to accelerate the motorcycle = 4.22 seconds

    final speed motorcycle reach = 28 m/s

    initial speed of motorcycle = 0 m/s

    Formula to calculate

    average acceleration = Δv / Δt

    = finalspeed - initialspeed / 4.22

    = 28 - 0 / 4.22

    = 28/4.22

    = 6.64 m/s²
