Im dropping parachutes out of a window with different weights on, up to a certain weight where the kenetic energy becomes too high. Then I am going to try to design a better shape to reduce the KE of the impact for that weight.

I know the surface area of my parachutes, the weight of the load hanging off the parachute, i also know the distance it is falling, and the time it took it to fall.

Im not too sure how to work it out at the moment i haven't put enough thought into it obviously.

I need to know Kenetic energy of the impact, the velocity it hits the ground with, and maybe its acceleration. Can i work it out from this? I was told something about stokes' law, the GPE and the amount of force disapated on its journy, the remaining would be the KE of the impact. But I am not sure what equations or how to use them.

I kinda need the advice asap!

If anyone could give me a bit of advice with what I am trying to do i'd be greatful.

Thanks alot!
