Final answer:
To boost a spacecraft from 2700 m/s to 5500 m/s in 45 s, the average acceleration is 55.56 m/s².
Step-by-step explanation:
To calculate the average acceleration to boost a spacecraft from 2700 m/s to 5500 m/s in 45 s, we can use the formula:
Acceleration = (Final velocity - Initial velocity) / Time
Substituting the given values:
Acceleration = (5500 m/s - 2700 m/s) / 45 s
Acceleration = 55.56 m/s²
Therefore, the average acceleration to boost the spacecraft is 55.56 m/s².
