Answer: 2.67 k/s^2
Step-by-step 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
