    Answer:

    i) 0\,\frac{m}{s^{2}}, ii) The object will not stop, as known acceleration is not different from zero.

    Explanation:

    i) When an object has a constant velocity, it means that both magnitude and direction of velocity does not change in time. Acceleration is the rate of change of velocity in time, as velocity is constant, acceleration must be zero. (0\,\frac{m}{s^{2}})

    ii) The object will not stop, as known acceleration is not different than zero.
