Do we know at what altitude he hit Mach 1.0, out of curiousity?
- gort 14y agoBack of envelope calculation: A. Starting height = 39045 m B. Desired speed = 343 m/s C. Acceleration = 9.8 m/s/s D. Average speed while accelerating = 171 m/s (half of B) E. Time to reach desired speed = 35 s (B divided by C) F. Therefore distance travelled = 5985 m (D times E) G. Therefore altitude at Mach 1 = 33060 m, give or take the small amount of drag. Edit: Meh, I see from the video that he didn't accelerate as fast as this, I guess the drag was significant after all. Even a small amount of gas will move you if it's coming at you at significant speeds...
- shasta 14y agoI think he meant altitude at which he was slowed back to mach 1.0.
