SUMMARY
The discussion centers on determining the correct value for 'v' in the drag equation, drag = kv^2, when predicting the peak altitude of a model rocket. The consensus is that 'v' should represent the velocity of the rocket relative to the surrounding air, incorporating all forces acting on the rocket, including thrust, gravity, and drag. The user, Andrea, initially confused about whether to consider the motor's force or the actual velocity, clarified that the velocity must account for air resistance. Ultimately, it was advised that incorporating drag into calculations may be complex due to the presence of two unknowns: the force due to drag and the actual velocity.
