    Answer:

    Acceleration, a=2\ m/s^2

    Explanation:

    We have,

    Initial speed of an object is 30 m/s

    It accelerates to a velocity of 55 m/s over a time of 12.5 s

    It is required to find the acceleration experienced by it. The rate of change of velocity is called acceleration of an object. It is given by :

    a=\dfrac{v-u}{t}\\\\a=\dfrac{55-30}{12.5}\\\\a=2\ m/s^2

    So, the acceleration of the object is 2\ m/s^2.
