V=30km/s , rotaton of the earth

i think we're not rotating with the earth. if we do, what is the reason? gravity? enclosed space? like when we're in a bus/car, that sort of thing? but the earth isnt enclosed.
my guess is because we're so small, the earth so big. and it is rotating at such a slow speed. if we were to jump off high enough and long enough im sure we'd b able to land in a different spot. but that isnt possible because of other factors. like wind. or if we're to use a rocket, no way it can be 100% accurate shooting straight up and down.

It is a characteristic of uniform motion. You don't land in a different place for exactly the same reason that if you toss a ball up inside a vehicle traveling at a steady 70 mph, it will come down in the same place - and not bash into the rear window. Everything on the surface of the earth is moving at a uniform speed along with the earth - and unless it is acted upon by a different force, it will continue to move at the same rate, even if it "jumps" off the surface.
Note: This is not true if the speed is not uniform - for instance, if you accelerate that same vehicle while the ball is in the air - it will indeed land behind you as the vehicle moves at a greater rate out from under the ball - and, conversely, if you hit the brakes while the ball is in the air, it will continue to travel forward and land in front of you.

Newton's First Law of Motion: Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
Imagine you are on a bullet train traveling at a constant speed of 200 kph. What happens when you jump? Do you suddenly slam into the back wall? No. Why? Because your inertia keeps you in motion with the train.
We are rotating with the Earth, so we stay in rotation at the same speed. By the way, Earth rotation is less than 0.5 km/sec, even at the Equator. Your figure of 30 km/sec is the orbital speed of the Earth around the Sun. The Sun (and the Earth and all of us) is also rotating in the galaxy at about 217 km/sec. The Milky Way (and the Sun, Earth, all of us) are traveling at about 600 km/sec relative to nearby galaxies. It's a wonder we don't get sick!
Similarly, although we are traveling, with the Milky Way, a distance equivalent to over four times the distance between the Sun and Pluto, we are oblivious to it.

Because you're also moving at the same speed as Earth rotates. If you jump from a car that's going 60 mph you'd also be going 60 mph, at least until gravity and air resistance slowed you down.

provided that have been to be conceivable, we could have saved a variety of of capability!!... we could have have been given the planes to 'waft' from the floor on a particular element and since the earth grew to become we could 'land' the airplane on the reqd. area. Sounds great, does not it?? yet unquestionably, thats a different equation all mutually! notwithstanding in case you 'leap' from the earths floor, there is something referred to as as "Gravity" which will shop you binded in the direction of the centre of the earth. so a techniques as you're under that's effect, you will circulate co-axial with the exterior. yet on the different hand in case you could desire to be precisely on the North/ South pole, because of the fact you would be on the pole, the tip results of rotation is minimum. lower back even this might properly be a great-human preposition because of the fact the physique being placed on the pole desires to be SO huge that it desires to negate the flatness of the earth's sphere and desires to be supported with the two a element/ line of touch on the earth.

Actually you do land at a location slightly different than where you first jumped from, because you were briefly at a greater distance from the center of the earth than the surface. Its just too small to measure.

No.
You are rotating with the Earth.
So, relative to the Earth, you come down where you took off from.

u r with same acceleration as that of earth!
so u r stationary with respsct to earth!
so!
