    Answer:

    B

    Explanation:

    v = vo + at

    200 = 0 + a*5

    200 = 5a

    a = 200/5 = 40 m/s²

    initial velocity (vo) is 0 because it says it start from station

    Answer:

    b. 40m/s2

    Explanation:

    Acceleration is calculated by dividing velocity over time. Therefore 200m/s by 5s equals 40m/s2
