does it have 2 drop and at was speed

when an elevator drops with the speed of gravity you will be weightless (to the elevator and your feeling) only thing> it should drop very fast..... (in the 1st second 10 meters, the 2nd second 20 meters and so on)
drop a rock from a building and see the speed of that, the elevator needs to be the same speed

You will not experience weightlessness in an elevator. Weightlessness can only be experienced when there is no gravitational field.
However, if the elevator goes down at the speed of g (accelartion around 10 meters / second /second) there will be no reaction between you and the floor of the elevator, since you will be free falling (ie falling towards the earth due to its pull). This is not the same as being weightless.

If elevator will moves down the same speed as U do, then it'll be the same as u jump into shaft without elevator. U cannot feel weightlessness.

You have just discovered relativity. If you and the car are accelerating at the same rate under the influence of gravity you are weightless compared to the car.
You are weightless compared to your frame of reference - the elevator car. However, when you and the elevator car hit the ground you will both run into a less accommodating frame of reference.

After initial acceleration the speed needs to be near 220k's per hour downwards, obviously.
They use specially designed planes and flight patterns to train astronauts doing a similar thing. Inside the plane appears wieghtless but outside, the plane is diving towards the earth at 220+k's per hour. Needless to say this flight does not last very long.

there is an entertainment park holiday in Conneaut Lake, Pennsylvania talked approximately as the "devil's Den". interior, you're spun around and the floor is released and your restraints are bumped off, yet you're pinned to the wall. besides, whilst the holiday includes an end, it spins down and only in the previous the floor meets your ft, you adventure some short seconds of simulated weightlessness. it somewhat is fairly cool. To adventure actual weightlessness, you're able to could desire to bypass up in that plane they that simulates it, which replaced into stated.

you can feel weightlessness if elevator is falling freely, under acceleration due to gravity.

drop with an acceleration of 9.8m/sec squared or 32 ft/sec.squared. means the speed should increase at that rate

Yes ELEVATOR has to drop at zero metre per sec

The lift should come down at 10 meters per second - you will feel as if you are in space - but you will not find such lift unfortunately.
