i think it would! yet it would have to spin very fast, lol
i think that if it got to around a prefect speed, you could have no gravity! :P:P though days would be very short . hope i helped :P
it would not cancel out gravily, but just hide it

Yes, but only at the equator. There, the centrifugal force would be straight up and the gravity straight down. At other places, the gravity would continue to act towards the centre of the earth, but the centrifugal force would act at 90 degrees to the earth's axis, so the two would not cancel each other. Living at the latitude of New York or Paris, it would feel as if there were a force pulling you southward, and walking north would be like walking up a steep hill.

Good question. It depends on the subjects starting point. If the subject starts on Earth, it's believable to me that spinning the Earth faster would spin the subject outward toward space, but the gravity would still pull the subject toward earth causing the subject to orbit with earth... the subject would seem to have zero weight, when in fact it is in orbit, even if only 2 feet off the ground.....
Contrast this with an object that isn't on Earth... lets say it's heading toward Earth and Earth is already at an accelerated speed. Let's say the object was a UFO and approached the Earth's surface like a helicopter making a soft landing. (I'm Excluding the state of air and wind) As soon as the UFO touched the ground, it would shoot back into space, (it'd just blow up though) because the ground was moving so fast... a mountain would have hit it like a raquet hitting a tennis ball.
Well, that's my best theory.

No, because if centrifugal canceled gravity there would be no force to hold the earth together. And, hence, there would be no gravity left for centrifugal to cancel.

Not really, if you spin the earth fast you would probably be thrown out of it (similar effect when you dipp a ball in water and spin it fast), but it wouldn't cancel out the gravity, gravity will still hold the moon and man made satellites that orbit around earth.
nice question i thought abt this some days back with a little difference, like if we increase the earth rotation speed a bit, we would probably be consuming less energy, less energy to move things around. less energy to launch rockets, less energy for our body to walk around earth. but should think about other implications.

Because gravity would be null at the surface, the surface of the planet would, well, leave - the heat and pressure pressing up on it from below is simply too great. So, yes, technically it would work...but the planet would fragment in the process, as well as most likely losing its atmosphere.

Yes, and it would cancel out Earth as a planet as well.
Obviously, though, gravity would be the same at the poles.

nothing can cancel out gravity my friend.
