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.

    Recently a 94 year old man died that had a hobby where he had progressed from sky diving to free falling from extreme heights. Before he died he had done 4 jumps out of a hot air balloon from 100,000 ft. I was wondering how long the ride was (not taking into account the parachute deployment.) Thanks for providing this!

    I fell 40 ft off the top of a quarry when I was 20 years old and was curious about the data . Fell feet first, clipped a ledge on the way down. Broke my heel bone, ankle and my foot. Spent a week in hospital. I was in bad shape.

    Joe Meanen, jumped 175 feet from a platform on Piper Alpa in 1989 it was said that his fall took 7 seconds to hit the water, this calculator says 3.3, I'm never going to reveal this as he earned his story, I if he said an angel broke his fall, I'd just agree and buy the man a pint...

    wanted to see how long it would take a 10,000 pound nuke to fall from 65,000 feet. For a thing I'm writing :)

    trying to figure out how fast a non- areodymamic box dropped in a pressurised chamber (Pressure from sea level) would fall genuinley because I'm interested. Couldn't say freom space as the stmosphere literally doesn;t extend that far. Thanks fro the help

    Trying to figure out how fast I was going when I fell backwards 15 feet and broke myself.

    Saw movie with a parachutist jumping at 2,000 ft agl and wondered how long they’d fall (~15 sec, movie scene was about 60 sec from jump to chute deployment. Hollywood, sheesh.)

    Checking I got the correct form for v(t) starting from Newton's Second Law. I got it right, I can still integrate!! Aha ha ha. 34 years after graduating.
