    Answer: 2.67 k/s^2

    Explanation:

    Given that:

    Initial velocity V1 = 1.0 k/s

    Final velocity V2 = 1.8 k/s

    Time taken T = 0.3 seconds

    acceleration of the meteoroid = ?

    Since acceleration is the rate of change of velocity per unit time

    i. e acceleration = (V2 - V1) / T

    Acc = (1.8 k/s - 1.0 k/s) / 0.3 seconds

    Acc = (0.8 k/s / 0.3 seconds)

    Acc = 2.67 k/s^2

    Thus, the acceleration of the meteoroid is 2.67 k/s^2
