Rocket Propulsion
Not what you're looking for?
A single-stage rocket is fired from rest from a deep-space platform, where gravity is negligible.
If the rocket burns its fuel in a time of 50.0 s and the relative speed of the exhaust gas is 2100 m/s, what must the mass ratio mo/m be for a final speed v of 8.00 km/s (about equal to the orbital speed of an earth satellite)?

Following is the text part of the solution. Please see the attached file for complete solution. Equations, diagrams, graphs and special characters may not appear correctly here.
Let q be the rate at which the exhaust gas is emitted.
After a time t, the mass of the rocket is reduced by M - qt where M is the initial rocket mass.
At time t + dt, let the velocity of ...
