hi I am currently doing my a-level A2 coursework on prachutes. I am using different size parchutes and also different masses attatched to them. However I want to work out the grad coeeficient, and have sort of combined a couple of equations to get:(adsbygoogle = window.adsbygoogle || []).push({});

mass*gravity = 0.5 * density of liquid * area * drag coefficient.

Is this right??? If it is I can calulate the grag coefficient by rearanging the equation and finding out the variables experimentaly. However I think that I may be mixing kinematics with dynamics in a way which is not allowed.

Thanks very much.
