Free fall with air resistance (time and velocity) Calculator

Calculates the free fall time and velocity with air resistance from the free fall distance.

The default value of the air resistance coefficient, k=0.24(kg/m), assumes the value in skydiving.

    Calculating time and speed of impact for two characters weighing a combined 280 lbs to fall off of the top of an 800 foot tall dragon spire that exploded because we can't leave ancient primal magics well enough alone.

    We lived.

    Purpose of use
    Used to calculate free fall times for a scene in my upcoming 5th novel, "Ceres" and for my 6th novel as well. Think "Adama Maneuver" but not with a battlestar. Time to Impact data let me know how long my pilot had to get the 'H.G. Wells' under control so that the First Temporal Marines could be deployed. Thank you.
