When you first leave an aircraft you are moving at the same speed as the aircraft which is typically 80-110 mph/130-180km. During the first 9-10 seconds the skydiver accelerates to what is called terminal velocity. You can alter your body position (decreasing or increasing surface area) to slow or speed up descent and experienced skydivers can reach fall rates over 200mph and there are records of speeds over 300mph (490km). However, in a standard belly-to-earth position used in student training and most skydiving, you will typically fall at a rate of anywhere between 100-140mph (180-220km).
Once the parachute is open, descent rates slow down to about 20 miles per hour or less under a straight flying, standard size parachute. Variables are achieved with different weight loading and aerial maneuvers.

Skydivers reach terminal velocity (around 120 mph for belly to Earth orientations, 150-200 mph for head down orientations) .

the internet rigidity decreases simply by fact if it greater, s/he could proceed accelerating and not in any respect gain terminal velocity, if it remained unchanged s/he could proceed on a similar velocity and not improve up (i.e while s/he's at terminal velocity, not earlier), so by technique of removal internet rigidity would desire to shrink. Acceleration decreases, if it did not terminal velocity could be impossible to realize. that's simply by fact simply by fact the value will strengthen, so does air resistance and while air resistance and weight stability, acceleration is 0.

I was always told 32 feet per second, with minimum wind resistance. Father built watertowers and watched a few, take the dive.

If they have a 5000 kg rock attached, probably 600 kmph

9.8 m/s^2
this is equal to the accelaration caused due to the earth's gravitational pull
when these two accelarations are equal, its is called terminal velocity

The question should not be how quickly do they fall, but do they bounce?
