You're missing a crucial piece of information: the acceleration rate! To calculate the change in velocity, we need to know how many meters per second squared (m/s²) the rocket is accelerating at.

Here's how you can calculate the change in velocity once you have the acceleration:

1. Convert time to seconds:

* 2 minutes * 60 seconds/minute = 120 seconds

2. Use the formula:

* Change in velocity (Δv) = acceleration (a) * time (t)

* Δv = a * 120 seconds

Example:

Let's say the rocket accelerates at 10 m/s².

* Δv = 10 m/s² * 120 seconds = 1200 m/s

So, the change in velocity would be 1200 m/s.
