The gezzer that jumped from a baloon,,, question? Born hunter , anybody else

[TOMO 27,147]

Ok so the fella that jumped yesterday , reached a speed of 833 mile an hour,,,,,, I always thought terminal valocity was around 150,,,,

 

Anybody have any answers ?...

[Chid 6,639]

he reached them speeds due to the less dense air

Based on wind resistance, for example, the terminal velocity of a skydiver in a belly-to-earth (i.e.:face down) free-fall position is about 195 km/h (122 mph or 54 m/s).^[2] This velocity is the asymptotic limiting value of the acceleration process, because the effective forces on the body balance each other more and more closely as the terminal velocity is approached. In this example, a speed of 50% of terminal velocity is reached after only about 3 seconds, while it takes 8 seconds to reach 90%, 15 seconds to reach 99% and so on.

Higher speeds can be attained if the skydiver pulls in his or her limbs (see also freeflying). In this case, the terminal velocity increases to about 320 km/h (200 mph or 90 m/s),^[2] which is almost the terminal velocity of the Peregrine Falcon diving down on its prey.^[3] The same terminal velocity is reached for a typical .30-06 bullet dropping downwards—when it is returning to earth having been fired upwards, or dropped from a tower—according to a 1920 U.S. Army Ordnance study.^[4]

Competition speed skydivers fly in the head down position and reach even higher speeds. The current world record is 1342.8 km/h (833.9 mph, equivalent of Mach 1.24) by Felix Baumgartner who skydived from 24 miles above earth on 14 October 2012. The record was set due to the high altitude where the lesser density of the atmosphere decreased drag. ^[5]

An object falling toward the surface of the Earth will fall 9.80655 meters (or 32.18 feet) per second faster every second (an acceleration of 9.80655 m/s² or 32.18 ft/s²). The reason an object reaches a terminal velocity is that the drag force resisting motion is approximately proportional to the square of its speed. At low speeds, the drag is much less than the gravitational force and so the object accelerates. As it accelerates, the drag increases, until it equals the weight. Drag also depends on the projected area. This is why objects with a large projected area relative to mass, such as parachutes, have a lower terminal velocity than objects with a small projected area relative to mass, such as bullets.

Mathematically, terminal velocity—without considering buoyancy effects—is given by there you go tomo

Terminally velocity is where the downward force of gravity, equals the air resistance. ie the drag. Well I think that's how it works.

Not got a clue Tomo,but that guy must have some serious bollocks to do that,the footage was unbeleivable they said the biggest danger was him going into a spin and not being able to recover

[stewie 3,387]

true chid but to that id add that the magnitude of terminal velocity depends on the weight of the falling body. For a heavy object, the terminal velocity is generally greater than a light object. This is because air resistance is proportional to the falling body's velocity squared. For an object to experience terminal velocity, air resistance must balance weight. An example that shows this phenomenon was the classic illustration of a rock and a feather being dropped simultaneously. In a vacuum with zero air resistance, these two objects will experience the same acceleration. But on the earth this is not true. Air resistance will equal weight more quickly for the feather than it would for the rock. Thus the rock would accelerate longer and experience a terminal velocity greater than the feather.

Another factor that affects terminal velocity is the orientation at which a body falls. If an object falls with a larger surface area perpendicular to the direction of motion it will experience a greater force and a smaller terminal velocity. On the other hand, if the object fell with a smaller surface area perpendicular to the direction of motion, it will experience a smaller force and a greater terminal velocity.

The terminal velocity for a skydiver was found to be in a range from 53 m/s to 76 m/s. Four out of five sources stated a value between 53 m/s and 56 m/s. Principles of Physics stated a value of 76 m/s. This value differed significantly from the others. Then again, the value is variable since the weight and the orientation of the falling body play significant roles in determining terminal velocity. but thats just my opinion mate.........

ok

[paulus 26]

so he basically, he fell to earth very quickly did a few barrell rolls in the process and then his parachute opened, he landed and lived happily ever after

Yip thats my view on it.............another pointless f*****g task from these space freaks!!

Read on, you might learn something useful instead for a change instead of filling your brain with pish like X factor and big brother..

[ELLE 7]

was listening to my dad and bunch of his mates debating this last night , they reckon it was" a fake like the moon landing " they were saying that surely opening a chute at those speeds would cause massive internal injuries ,would break your neck ,back ,shoulders etc , that the ropes on the chute would snap .. dont know but maybe they have a point

I learned that a guy can jump from pretty much space and he will fall pretty god dam fast....who would have thought that eh... Maybe a better thing would have him to have no parachute and see how far he went underground when he hit the bottom.........

Oh and X Factor and BB are factual enough for me.....i've learned that the country is full of Gay weirdos voting for Rylan............... :censored: I hear Wilf has spent a near fortune on saving him alone........
