Terminal velocity is the maximum speed attainable by an object as it falls through a fluid (air is the most common example). ... from 2,900 miles per hour ...
In stable, belly-to-earth position, terminal velocity is about 200 km/h (120 mph). Stable freefall head down position has a terminal speed of 240–290 km/h (around 150–180 mph). Further minimization of drag by streamlining the body allows for speeds over 500 km/h (310 mph).
Escape speed at a distance d from the center of a spherically symmetric primary body (such as a star or a planet) with mass M is given by the formula [2] [3] = = where: G is the universal gravitational constant (G ≈ 6.67×10 −11 m 3 ·kg −1 ·s −2)
[16] [4] Aikins reached a terminal velocity of 120 miles per hour (193 km/h) during the fall. [14] The net was made from Spectra , a high-density polyethylene cord. [ 17 ] It had four compressed air cylinders designed to gently slow him down after impact. [ 17 ]
Red Bull Stratos was a high-altitude skydiving project involving Austrian skydiver Felix Baumgartner.On 14 October 2012, Baumgartner flew approximately 39 kilometres (24 mi) [1] [2] [3] into the stratosphere over New Mexico, United States, in a helium balloon before free falling in a pressure suit and then parachuting to Earth.

With air resistance acting on an object that has been dropped, the object will eventually reach a terminal velocity, which is around 53 m/s (190 km/h or 118 mph [4]) for a human skydiver. The terminal velocity depends on many factors including mass, drag coefficient , and relative surface area and will only be achieved if the fall is from ...

A recreational wind tunnel enables human beings to experience the sensation of flight without planes or parachutes, through the force of wind being generated vertically. Air moves upwards at approximately 195 km/h (120 mph or 55 m/s), the terminal velocity of a falling human body belly-downwards. A vertical wind tunnel is frequently called ...
