Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity. It can be calculated by the expression:

a = v2 - v1 / t

From the given in the problem, we can solve for v2, the final velocity:

3 = v2 - 0 / 300

v2 = 900 m/s
