a max speed of 290kmh if you form you self lie a bullet but if you lie out 200kmh
Answer:
There is no specific speed for free fall. It is dependent on many factors including the local attraction of gravity, air density, cross sectional area presented to the air flow and mass of the falling object. As a result cats can fall from tall buildings and not be hurt while people or ponies are reduced to a red mess.
We have to impose three conditions/assumptions:
1). The object was dropped from rest, not throwndown; so when the 30 seconds began,
the object had no downward speed yet.
2). We have to ignore the effects of air resistance, because they're complicated, and they
depend on the shape of the object, which we don't know anything about.
3). We assume the whole experiment is carried out on earth.
With those 3 assumptions, the free-falling object falls 4,410 meters in 30 seconds.
(About 14,470 feet).
Notice that contrary to what some die-hards are still telling you, and writing on this
website, the mass or weight of the free-falling object makes no difference.
Since you're accelerating in free fall, each 30 meters takes less time
than the last 30 meters took.
If you're content to talk about the first 30 meters after you roll out of
the airplane, then the formula is
H = 1/2 G T2
H = 30
G = 9.8
30 = 4.9 T2
T2 = 30/4.9
T = sqrt(30/4.9) = 2.47 seconds (rounded)
There is a limit to how fast you can fall though, due to friction with the air. The average terminal velocity of a skydiver is about 63 m/s2. At this speed it would take about 0.476 seconds to fall 30 meters.
If air friction were not involved, then it would take a little over 43 seconds to free fall 30,000 feet. However, air friction limits the speed at which you fall to a maximum of about 120 miles per hour. It takes you about 5.5 seconds to reach terminal velocity, during which time you will fall only about 490 feet. It will then take you about 166.5 seconds to fall the rest of the 30,000 feet, for a total time of 172 seconds, or 2 minutes and 52 seconds.
At terminal velocity, a skydiver reaches around 200mph. The world record is 614mph which was set by Joseph Kittinger.
We have no idea of the shape or size of what's falling,
so we have to ignore air resistance.

T = sqrt(3,000/16.1) = 13.65 seconds

A 4-inch diameter pipe that is 3,000 feet long has a volume of: 261.8 cubic feet.
There are 3 feet in one yard. Therefore, 3000 feet is equal to 3000/3 = 1000 yards.
there are 5280 feet in a mile so it should take 5280 seconds which is about an hour and 28 minutes
25% of 3,000 square feet= 25% * 3000= 0.25 * 3000= 750 square feet
300 ft by 3000 ft is approximately 20.661157 acres, as you would multiply 300 by 3000 (as acres are a unit of area, not length) giving you 900,000 square feet (sqft, or ft2) which converts to about 20.661157 acres, as an acre is 43560 square feet.
