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
