Baumgartner's team estimates the Austrian sky diver and helicopter pilot will reach Mach 1. Originally scheduled for Monday but postponed due to projected high winds, the feat would make him the first human to break the sound barrier without the propulsion, or protection, of a vehicle. The current free fall record is held by Joseph Kittinger , a retired U. Air Force colonel and current Red Bull Stratos team member, who fell See classic pictures of Kittinger's skydive.
Kittinger, after years of refusing to help see his record broken, is now enthusiastically behind Baumgartner. He's a trained athlete, he's an aviator. Baumgartner agrees: "[Joe] knows how lonely you are at that altitude. But things can go wrong. All rights reserved. Share Tweet Email. Why it's so hard to treat pain in infants.

India bets its energy future on solar—in ways both small and big. The data from the jump was collected every 2 seconds, for the first 5 minutes of the jump, and then every 10 seconds after that, until landing.
The spreadsheet of jump data may be edited. You can give your students some or all of the data and you could ask them to analyze it by: Calculating an average speed for the jump. Calculating the acceleration. Graphing distance vs. Graphing speed vs. Calculating and graphing acceleration vs. Interpret student-made graphs or use the pre-made examples from the attached data. There are several ways you might wish to use these graphs: Use the graphs to describe the jump and label key moments including acceleration, deceleration, travel that occurred faster than sound, terminal velocity, parachute deployment, the transition from stratosphere to troposphere, and the landing.
Note key moments based on the relative size and direction of the forces acting on Felix. Calculate speed by determining the slope at any point on an altitude vs.
Calculate acceleration by determining the slope at any point on a speed vs. Calculate acceleration using the speed and time data. Determine distance travelled, by calculating the area under some or all of a speed vs.
