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.

[1]  2019/01/09 22:41   Male / 60 years old level or over / An engineer / Useful /
Purpose of use
Checking time and distance required to hit 85 km/h when jumping off the Auckland Sky Tower.
[2]  2018/12/21 08:47   Male / 20 years old level / An engineer / Very /
Purpose of use
Calculate how long Alex Honnold would be in free fall if he fell off 3/4 the way up El Cap. 18 Seconds is a long time to think about your mistakes.
[3]  2018/12/21 07:34   Male / 30 years old level / High-school/ University/ Grad student / Very /
Purpose of use
Paragliding or hang gliding reserve parachutes are rated in terms of opening time. Want to determine minimum safe height of deployment given that period of opening time (assuming worst case, being freefall)
[4]  2018/12/06 07:13   Male / 20 years old level / An engineer / Very /
Purpose of use
Wanted to see how fast that girl who got pushed off a bridge by her friend was falling when she hit the water. About 42 mph
[5]  2018/11/18 18:45   Male / 20 years old level / Others / Very /
Purpose of use
counterweight velocity baseline
[6]  2018/11/10 13:09   Male / 20 years old level / An engineer / Useful /
Purpose of use
Calculating if a flying character in D&D would hit the ground in 1 standard 6 second round if he fell. he would.
[7]  2018/09/28 17:14   Male / 20 years old level / An office worker / A public employee / Very /
Purpose of use
I'm watching skyscraper with the rock and wanted to see how long it would take him to hit the ground if he fell in the movie
Comment/Request
Good program. The other didnt calculate air resistance
[8]  2018/09/07 10:39   Male / Under 20 years old / High-school/ University/ Grad student / Useful /
Purpose of use
Calculating the length of time the guy who fell off of a waterfall at yellowstone was likely falling for before he hit the ground (~8.43 seconds)
[9]  2018/08/24 13:59   Male / 30 years old level / An office worker / A public employee / Useful /
Purpose of use
Determining amount of air time before a Fey RPG character would hit the deck on an airship.
[10]  2018/08/23 07:22   Male / 20 years old level / High-school/ University/ Grad student / Very /
Purpose of use
Calculate free fall time of my friend vomiting out of a 40th floor window in Toronto. 62 second!!!
