Final answer:
The average acceleration of the spaceship is 162.5 m/s².
Step-by-step explanation:
To find the average acceleration of the spaceship, we can use the formula:
average acceleration = change in velocity / change in time
The change in velocity is given as 1300 m/s - 0 m/s = 1300 m/s. The change in time is given as 8.0 s - 0 s = 8.0 s. Plugging these values into the formula:
average acceleration = 1300 m/s / 8.0 s = 162.5 m/s²
Therefore, the average acceleration of the spaceship is 162.5 m/s².
