A speed record is a world record for speed by a person, animal, or vehicle. The function of speed record is to record the speed of moving animate objects such as humans, animals or vehicles. The function of speed record is to record the speed of moving animate objects such as humans, animals or vehicles.
The Apollo 10 crew (Thomas Stafford, John W. Young and Eugene Cernan) achieved the highest speed relative to Earth ever attained by humans: 39,897 kilometers per hour (11,082 meters per second or 24,791 miles per hour, about 32 times the speed of sound and 0.0037% of the speed of light). [14] The record was set 26 May 1969. [14]
The speed, achieved by the human body in free fall, is a function of several factors; including the body's mass, orientation, and skin area and texture. [1] 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).
During this descent Baumgartner set the record for fastest speed of free fall at 1,357.64 km/h (843.6 mph), [2] [12] [5] making him the first human to break the sound barrier outside a vehicle. [ 38 ] [ 39 ] Baumgartner was in free fall for 4 minutes and 19 seconds, a fall time 17 seconds shorter than the record set during mentor Joseph ...
At 65,589 feet, Apt beat all previous records speed records, reaching Mach 3 (2,094 miles per hour). He was the fastest flying man alive and would hold the record until 1961, when the X-15 reached ...
Its predecessor, the Alfa class, could attain short speed bursts of 40–45 knots (74–83 km/h; 46–52 mph) while submerged. [ 4 ] [ 5 ] There are also claims that the Soviet twin-propeller submarine K-222 , with titanium inner and outer hulls , reached 44.7 knots (83 km/h; 51 mph), fully submerged, during sea trials in 1969.
Speed of propagation for unmyelinated sensory neurons. 30: 110: 70: 1 × 10 −7: Typical speed of car (freeway); cheetah—fastest of all terrestrial animals; sailfish—fastest fish; speed of go-fast boat. 40: 140: 90: 1.3 × 10 −7: Typical peak speed of a local service train (or intercity on lower standard tracks). 40.05: 144.17: 89.59: 1. ...
