im to design something, a plane, or any kind of material to let it stay from the time of release up to it falling into the ground for 13 seconds provided that it is powered by a rubber band... i'm having a hard time thinking about it, having it stay in mid-air longer than usual, and just want...

I got bored in the airplane and took a video of us taking off from LAX to Regan National. We were in a brand new 737-800, Alaska Airlines. It was a really nice flight. No one sat next to me and I had 3 seats to myself and stretched my legs across all three of them. :rolleyes: Lots of...

Would QM fail in the fast moving satellite or Int. Space Station if I conducted the double slit experiment in the space station, which is traveling allot faster then most jets. This would be like the clocks experiment where both times were different; the one on the plane being allot slower then...

Jetman! Individual flight http://www.jet-man.com/actuel_eng.html Watch the video. Incredible! I want I want I want...now! now! now! :-p

Well, we all read the "abreviated" version of this story. How many read all the facts of what really happened? Quite a different story. Excellent opinion piece from the WSJ. The information seems to be corroborated by the following CNN article with interviews of passengers saying the same...

Stupid question: can people fly? Evidently, one doesn't see people flying around the streets, but is it possible? Has anyone done studies on whether this is possible or not? Any articles on this would be highly appreciated. Has anyone actually done this? Furthermore, how does physics apply to...

A airplane flight at 2700 miles is schduled to take 50 min longer westward than eastward. THe airspeed is 600 m/hr. What assumptions about the jet-stream wind velocity presumed to be east or west are made in preparing the schedule? (what is the wind speed?) I am going over Halliday and...

This is a problem from Cutnell and Johnson Physics I have set up my formula so that eventually I am solving a quadtratic equation, I am unsure if my calculations are correct, any input would be appreciated. THE QUESTION: An airplane is flying with a velocity of 240 m/s at an angle of...

The displacement from London, Uk, to Rome is 1400km [43 degrees E of S]. A wind is blowing with a velocity of 75km/h [E]. The pilot wants to fly directly from London to Rome in 3.5h. What velocity relative to the air must the pilot maintain? [p = plane, a = air, g = ground] Vpa + Vag = Vpg...

This is probably old news, but I've just seen the 2 flight 77 videos. Does anyone have a good idea of what the object is in the last frame before the explosion? http://www.dod.mil/pubs/foi/" http://pserver.mii.instacontent.net/defense/flight77/fl77-1_11094135.WMV"...

Hi. I'm a middle school student messing around with some paper airplanes. I am wondering how the size of the paper I use affects the properties of flight like distance and flying time and how well the plane flies. I tried a few sizes of paper and found a good one. What controls this? I know...

Hey If I were to climb a flight of stairs I would gain potential energy because I would be moving further away from the centre of the earth. However would I have more, less or equal amounts of kinetic energy at the top of the flight of stairs, or at the base and why would this be so? If what I...

if an aircraft with a coefficient of lift of 0.05322 is traveling at the velocity of 240 kts at sea level, how much lift is required to fly at level unaccelerated flight if the aircraft weighs 800 lbs? (hint: trick question)

I got this question on my physics test "What will happen if you blow over a piece of paper?" I answered that with enough blowing, the wind created would make the paper fly off. Apparently according to my teacher, the correct answer was that from Bernouilli's theorem, the air velocity above...

The table describes the flight of a toy glider launched from a tower on a hilltop. The values for height indicate the number of metres above or below the top of the hill. I have to find an algebraic model that gives height as a function of time. How do I do that? I have no idea where...
