- Purpose of use
- Calculation for A 14-year-old boy falling from a ride at an Orlando amusement park that takes passengers 430 feet in the air before plummeting toward the ground at 70 miles per hour,

- Purpose of use
- used it to calculate at what speed someone would fall at from a height of 36.36 metres out of curiousity, worked wonders : )

- Purpose of use
- A Japanese fishing boat in open water was sunk by a cow that fell out of the clear blue sky. Investigators determined the animal fell from a passing aircraft. I wanted to determine how long the aircraft had to clear the area before the ballistic bovine impacted the target. The answer was "not much". The aircraft would have still been visible to the fishermen if they had had the leisure to look for it while their vessel disintegrated around them.

- Purpose of use
- Dungeons & Dragons shenanigans. (We needed to find out how much fast a robot would be going after dropping 190ft to see if they could spear punch a iron chest.)

- Confirming a statement that was posted online.
- Comment/Request
- I see requests for adding complexity to defining the value of k.

I prefer your spherical cow approach. :)

- Purpose of use
- Rattling off a quick forum post about a hypothetical aviation incident, I did a quick and dirty mental arithmetic guesstimate on how long it would take a stationary object to fall to earth from a set height. Knowing how AvNerds are (because I am one, obviously) I thought it best to find an online resource to double check my maths before posting, to make sure I'm at least in the right order of magnitude with my answer. The only conclusion I can draw from this is that I must be using this calculator either incorrectly or for the incorrect purpose, perhaps the Air Resistance - which I didn't change - is something that both needs to be adjusted and is way beyond my comprehension. The aircraft part that "fell off" had a set weight, and from the altitude I set (working on the basis that the aircraft was stationary and the part had no momentum in any direction) the object fell with a speed around mach 1.4- making me think the calculations may be a teeny weeny bit out of line.
