Explanation:
Given:
- speed of rocket initially,

- top speed of rocket after acceleration,

- time taken to get to the top speed,

- final speed of the rocket,

- time taken to get to the final speed after reaching the top speed,

Now the acceleration:



Now as a fraction of gravity:


Now, the deceleration:


Now as a fraction of gravity:
