SUMMARY
A rocket accelerates from an initial velocity of 1,000 m/s at a constant rate of 20 m/s² for a duration of 2 minutes. To calculate the final speed, one must first convert the time from minutes to seconds, resulting in 120 seconds. Utilizing the SUVAT equations, specifically the formula for final velocity (v = u + at), where u is the initial velocity, a is acceleration, and t is time, the final speed reached is 5,000 m/s.
PREREQUISITES- Understanding of basic physics concepts, particularly kinematics
- Familiarity with the SUVAT equations
- Ability to perform unit conversions (minutes to seconds)
- Knowledge of acceleration and velocity definitions
- Study the SUVAT equations in detail for various motion scenarios
- Learn about the effects of mass loss on rocket acceleration
- Explore advanced kinematics problems involving variable acceleration
- Investigate real-world applications of rocket propulsion and acceleration
Physics students, aerospace engineers, and anyone interested in understanding rocket dynamics and acceleration calculations.

A pretty high "speep". I should imagine. It really is a shame it's so hard to edit the title of a thread 
Just use the right formula, remembering to convert minutes to seconds!

Assuming we don't lose any mass?
How many seconds are there in a minute? After that use you suvat equations to find the final velocity.
Your inital velocity is 1000m/s and you have an acceleration.
