Supersonic Jump
Earlier today, guy rode a balloon to an altitude of 128,000 feet, just over 24 miles above the earth's surface. He jumped after the two and a half hour ascent to free fall back to earth. It took 48 seconds for him to reach Mach 1, breaking the sound barrier. Top speed reached during his free fall was estimated to be 834 MPH. Very cool.

So we had this discussion at dinner. What is terminal velocity??

It depends on a lot of factors. Air density being the big one here. uploadfromtaptalk1350263600599.jpg

That came out crappy. Its....
V=sqrt(2mg/pAC)
M=mass in kg
G = acceleration due to gravity in this case 9.81 m/s^2
Rho(p) = density of the fluid in this case its air (yes air is a fluid)
A= cross sectional area (so for example if you were a square, your value here would be length*width)
C = drag coefficient (this is a constant, changes i.e. if you're wearing sandpaper vs wearing latex)2013 LSV

Cant believe the chute deployed 20 seconds before getting the freefall record. He jumped 30000 feet higher than kittinger and still didnt get the freefall record. Still ballzy but i would be pissed i didnt get the freefall record.

The argument was made that the lack in air density would be cancelled out by the reduced force of gravity being 24 miles up. It was based on 0 science and just people's opinions/thought.

So did he deploy the chute "early?"
