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.

    Purpose of use
    Trying to figure out how fast my drone will hit the ground (or someone) if it loses power at 4000m - apparently air resistance will keep it to a breezy 3 m/s.

    Purpose of use
    Approximating Gandalf's distance of fall when fighting the Balrog in the movie The Two Towers. It's about 13,000 feet, which compares plausibly to the rough sizes of a middling-large mountain.

    Purpose of use
    Determining time of fall for a role playing game.

    Purpose of use
    To determine how long it took Lafe McDaniel to hit the water when he fell from Navajo Bridge into the Colorado River in 1928.

    Research for a fiction book about military HALO jump.
    [6]  2022/09/05 13:58   20 years old level / An engineer / Useful /
    Purpose of use
    figuring out how tall of a fall would give enough time to drink a beer on the way down
    [7]  2022/09/02 19:10   40 years old level / An office worker / A public employee / Useful /
    Purpose of use
    watching a documentary about the x-15 flight 90 flying at 46 miles above the earth and was curious to find out how long it wold take to fall that distance
    [8]  2022/09/02 02:13   60 years old level or over / A retired person / Useful /
    Purpose of use
    Writing a story involving a near-fatal fall
