Hey,(adsbygoogle = window.adsbygoogle || []).push({});

I'm having some problems trying to solve the equasion for air drag. I'm currently doing a project about solidfuel rockets and air drag is a big deal =)

I used this equasion for dragforce (Fd)

Fd(t)= -0,5 * p * A * Cd (((Fm - Fg - Fd) / m ) *t)^2

which is just a lot of parameters so simplified this is:

Fd(t)= a * ((b-Fd)/c * t)^2

I'm not familiar with differential equasions at all but my math teacher told me this is one. To bad he couldn't solve it though.

Does anybody know how to solve this so it can be used to calculate dragforce Fd at time t?

Thanks ahead!
