    Solving Air Drag Equation for Beginners

    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)...

    Air Drag Formula: Solving Maik's Rocket Project Challenge

    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...

    Solving Air Drag Equation for Beginners

    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

    Solving Air Drag Equation for Beginners

    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...
