I'm sorry we must have misunderstood. If the link you posted is what you mean by quadratic equation then the formula above is no quadratic equation =) Please note that Fd(t) is to be filled into the function, not Fd as constant or t as constant. Fd(t)= a * (( b-Fd(t) )/c * t)^2 Fd(t)...

Hello, I'm working on a project about solid fuel rockets and since these are moving through the atmosphere, they experience Air-drag. I'm trying to set up a formula to exactly calculate the height a rocket will achieve. So without the use of any model. The problem I ran into is that I can't...

Hello smallphi, could you explain that showing the math? Because I can't come up with anything to solve an equation involving it's own answer: Fd(t)= a * (( b-Fd(t) )/c * t)^2 Regards, Maik

Hey, I'm having some problems trying to solve the equation for air drag. I'm currently doing a project about solidfuel rockets and air drag is a big deal =) I used this equation for dragforce (Fd) Fd(t)= -0,5 * p * A * Cd (((Fm - Fg - Fd) / m ) *t)^2 which is just a lot of...
