The troposphere is where airlines and airplanes fly, and is where air resistance builds up as the air molecules multiply, at an atmospheric pressure of around 25-40 HPA. The speed of sound is calculated as Mach 1. (690 mh-1), and Felix reached a speed of 843.60 mh-1, which is approximately Mach 1.25, which means he broke the speed of sound at around 40 seconds of the fall. After this breaking the speed of sound, he experienced unbalanced forces entering the troposphere, so instead of being stable and vertical, he was spinning out of control. This occurred due to the low air density, and its interaction with Felix. If Felix’s body is not in a symmetrical position during the fall (vertical or free fall position), the air can apply torque on his body, which causes him to spin. During the spin, Felix completed 4 complete spin revolutions in 3.44 seconds, and the spin lasted for 40 seconds, which means he spun 46.5 complete revolutions during this time. During the spinning time, he was at a terminal velocity of approximately 700 …show more content…
At approximately 3:30 minutes of the jump, Felix slows down, as the atmospheric pressure increases to 200 HPA. His velocity decreases to around 570 mh-1. However, this is at around 60,000 ft. (18,288 m), and he must slow down to 172 mh-1 before deploying the parachute, which is supposed to be at approximately 5,000 ft. (1,524 m). At 5,000 ft. (1,524 m) the, atmospheric pressure is approximately 750 HPA, and the velocity is approximately 120 mh-1 (193
