Acceleration is the rate of change of speed or velocity. This being said, we can calculate for the acceleration by dividing the given speed by the given time. That is,
               a = speed / time

Substituting the known value,
               a = 15 m/s / 3s
                a = 5 m/s²

Hence, the answer is 5 m/s².
