Answer:



Explanation:
The speed of the rocket is given the Tsiolkovsky's differential equation, whose solution is:

Where:
- Initial speed of the rocket, in m/s.
- Exhaust gas speed, in m/s.
- Initial total mass of the rocket, in kg.
- Current total mass of the rocket, in kg.
Let assume that fuel is burned linearly. So that,

The initial total mass of the rocket is:

The fuel consumption rate is:


The function for the current total mass of the rocket is:

The speed function of the rocket is:

The speed of the rocket at given instants are:
