The math behind Michael Jordans legendary hang time Andy Peterson and Zack Patterson
Michael Jordan once said, quot;I don't know whether I'll fly or not. I know that when I'm in the air sometimes I feel like I don't everhave to come down.quot; But thanks to Isaac Newton, we know that what goes upmust eventually come down. In fact, the human limit on a flat surface for hang time, or the time from when your feet leavethe ground to when they touch down again,
is only about one second, and, yes, that even includes his airness, whose infamous dunk from the free throw line has been calculated at .92 seconds. And, of course, gravity is what's making itso hard to stay in the air longer. Earth's gravity pulls all nearby objectstowards the planet's surface, accelerating them at 9.8 meters per second squared. As soon as you jump,gravity is already pulling you back down.
Using what we know about gravity, we can derive a fairly simple equationthat models hang time. This equation states that the heightof a falling object above a surface is equal to the object's initial heightfrom the surface plus its initial velocity multiplied by how many secondsit's been in the air, plus half of the gravitational acceleration multiplied by the square of the numberof seconds spent in the air. Now we can use this equation to modelMJ's free throw dunk.
Say MJ starts, as one does,at zero meters off the ground, and jumps with an initial verticalvelocity of 4.51 meters per second. Let's see what happens if we modelthis equation on a coordinate grid. Since the formula is quadratic, the relationship between heightand time spent in the air has the shape of a parabola. So what does it tell us about MJ's dunké Well, the parabola's vertex shows ushis maximum height off the ground
at 1.038 meters, and the Xintercepts tell us when he took off and when he landed,with the difference being the hang time. It looks like Earth's gravitymakes it pretty hard for even MJ to get some solid hang time. But what if he were playing an away gamesomewhere else, somewhere faré Well, the gravitational accelerationon our nearest planetary neighbor, Venus, is 8.87 meters per second squared, pretty similar to Earth's.
If Michael jumped here with the sameforce as he did back on Earth, he would be able to get more than a meter off the ground, giving him a hang time of a little over one second. The competition on Jupiterwith its gravitational pull of 24.92 meters per second squaredwould be much less entertaining. Here, Michael wouldn't evenget a half meter off the ground, and would remain airbornea mere .41 seconds. But a game on the moonwould be quite spectacular.
5 People Who Actually Jumped From Space
5 People Who Actually Jumped From Space 5.Joseph Kittinger Joseph William Kittinger is a retired Colonelin the United States Air Force and a USAF Command Pilot.Following his initial operational assignment in fighter aircraft, he participated in ProjectManhigh and Project Excelsior in 1960, setting a world record for the longest skydive froma height greater than 31 kilometres. He was also the first man to make a solo crossingof the Atlantic Ocean in a gas balloon. Joe Kittinger made history as he ascendedto 102,800 feet in a highaltitude balloon
and jumped to Earth, setting four world records.Of the jumps from Excelsior, Kittinger said: quot;There's no way you can visualize the speed.There's nothing you can see to see how fast you're going. You have no depth perception.If you're in a car driving down the road and you close your eyes, you have no idea whatyour speed is. It's the same thing if you're free falling from space. There are no signposts.You know you are going very fast, but you don't feel it. You don't have a 614mph windblowing on you. I could only hear myself breathing in the helmet.quot; 4. Eugene Andreev
Eugene Andreev was a colonel in the SovietAir Force. Andreyev set an official record for the longestdistance freefall parachutejump on 1 November 1962, which the Guinness Book of Records put at 24,500 meters.The record was previously held by Joseph Kittinger, but was stabilized by a drogue parachute.Andreyev was awarded the Hero of the Soviet Union for his feat.On 1 November 1962, Eugene Andreev jumped from an altitude of 25,458 m over the Sovietcity of Volsk. Opening his parachute at 958 m. He covered a record distance of 24,500m in freefall. 3. Nick Piantanida
Nicholas John Piantanida was an American amateurparachute jumper who reached 123,500 feet with his Strato Jump II balloon on February2, 1966, flying a manned balloon higher than anyone before.Nick Piantanida, a truck driver from New Jersey with a dangerous appetite for highrisk adventure;but with little experience or training; cobbled together sponsorship money, wangled a spacesuit with the help of a U.S. senator and assembled a team of volunteers for an attempt at theworld freefall record. Strato Jump launched perfectly on May 1, 1966,climbing past 50,000 feet without any problems. Everyone was relaxed, excited even. This wasgoing to work. And then, it didn't. Ground
control heard what was generally describedas a quot;whooshquot; of rushing air, a cutoff call over the radio and the deployment of an emergencyparachute. When the ground crew found Piantanida 26 minutes later, he was barely conscious.When he arrived at the , he had already lapsed into a coma.Piantanida suffered brain damage from a lack of oxygen and he died four months later atthe Veterans in Philadelphia. 2. Felix Baumgartner Felix Baumgartner is an Austrian skydiver,daredevil and BASE jumper. He broke skydiving records for exit altitude, vertical freefalldistance without drogue, and vertical speed
without drogue.Felix, born April 20, 1969, grew up in Salzburg, Austria where he dreamed of skydiving andflying helicopters and was inspired by astronauts on TV. He made his first skydive at the ageof 16. Eager to test the limits, Felix set a recordfor history's lowest BASE jump from Rio de Janeiro's Christ the Redeemer statue, twiceset world records for the highest BASE jump from Petronas Towers in Kuala Lumpur and Taipei101 tower, and even landed his canopy inside a cave in Croatia.He set world records for skydiving an estimated ' km, reaching an estimated speed of 1,357.64kmh on 14 October 2012, and became the first
