    Answer:

    0.01 m/s^2.

    Explanation:

    The formula for acceleration is Δ velocity/ Δ time or change in velocity/change in time. We can see find the change in velocity by subtracting v0 (initial velocity) from v (current velocity). v – v0 = 80.3 m/s – 80.1 m/s = 0.2 m/s. The change in time is already given, 20 seconds, so all you have to do is divide 0.2 m/s by 20 seconds to get 0.01 m/s^2.
