The upward velocity of a rocket can be computed by the following formula:
v=u (ln (m/m*q*t))-g*t
where v = upward velocity, u = the velocity at which fuel is expelled relative to the rocket, m= the initial mass of the rocket at time t=0, q=the fuel consumption rate, and g=the downward acceleration of gravity (assumed constant =9.81 m/s2). If u = 1800 m/s, m= 160,000 kg, and q =2600 kg/s, compute the time at which v = 750 m/s. (Hint: t is somewhere between 10 and 50 s.)

This sounds like a homework assignment. If it is, show what you've done to try to solve the problem and ask a specific question about where you're having difficulty and we may be able to offer guidance.
If you're not sure even where to start because you aren't sure how to work with MATLAB, I strongly recommend going through the MATLAB Onramp free tutorial which will help you learn the essentials of MATLAB programming.
If you're unclear about the question as a whole, I recommend contacting your professor and/or the teaching assistant for your course for clarification.
