Is it true that the maximum velocity of a human(without a parashute) jumping from a plane is 180mph?

Question

Uncle Al, whaat the hell is that in mph as in my Q?

Answer 1

It depends on a) body position b) external temperature c) air density. a) is the most important. By "standing up" in free fall, i.e, arms behind, legs together, an experienced skydiver can reach terminal speeds of between 170 and 180mph. Speeds of over 200mph require significant practice to achieve. The record free fall speed, done without any special equipment, is 321mph. Obviously, it is desirable to slow back down to 110mph before parachute opening."

Answer 2

Even more interesting, back in the late 1800's when scientists where studying fluid dynamics they did a series of experiments that involved dropping small animals down a very long mine shaft. As horrible as it sounds...It was found that a dog would break a lot of bones but still live, a cat would suffer some mild damage and be able to walk away, and a mouse would suffer only minor injuries and be able to run away after the fall. All due to terminal velocity.

Answer 3

Terminal velocity is in normal conditions approximately 120 mph. You can achieve higher velocities in certain circumstances but at the end of your fall you will hit the ground at about 120 mph.

Answer 4

Yes, this is called terminal velocity when drag bleeding off energy equals the input energy force of gravity.

And that is with someone diving head first with their arms and legs streamlined to the body at low altitude.

If you skydive from the edge of space you can break the sound barrier.

Answer 5

Google
"terminal velocity" human 101,000 hits

56-76 m/s depending on conformation.

Answer 6

At low altitudes, yes if you go head first and streamline your arms and legs as in a dive.

If you spread out your arms and legs in the usual skydiver pose you will slow to about 120mph.

Answer 7

I was told it was 250 mph.

Answer 8

terminal velocity--> equilibrium between gravity and air resistance
