Some things you could take into consideration are the weight of the jumpers. There height, well more like overall mass. Gravity would be another key factor. The angle at which she jumped could be another variable. Wind resistance could be another important thing. How far she is attempting to jump is an important variable.
Those are just some of the basic things.
