Aeronautical Engineering/Trajectory followup

Question
Sir,

As a follow up to the free body drawn and excess power eqn. deduced, its asked to compute the trajectory for the 1st 60 seconds of that flight. Given values are:

Reference area
Start weight
Weight at first stage burnout
First stage starting weight
First stage empty weight
Thrust
Burn time
And Cl, Cd values at angle of attack 0, 1.5, and 2.5 at mach nos. 0.5, 1, 1.5, 2, 2.5, and 3.

Been told to perform 4 trajectory analysis using the Cl, Cd data.

I understand its a long question but any help will be much appreciated.

Answer
Sorry, Jeff - I don't do homework problems. Sounds like you will have to set up the equations and integrate the trajectory after computing acceleration and velocities (or compute distance in a stepwise manner). The fact that you have a lift coefficient suggest that the vehicle is flying at some angle of attack.
