Not a whole helk of a lot. In the meantime, I have other issues I'm more concerned about.

It won't happen anytime soon, but there would be nothing we as humans could do.
Earth is rotating at a speed of about 1100 miles per hour. If our planet suddenly stopped rotating, the atmosphere would still be in motion at that speed. The atmosphere would be moving so fast it would literally sweep the land masses clear of anything not anchored to bedrock, this would mean rocks, soil, trees, buildings, people and animals. All would be swept up into the atmosphere.
If the Earth's rotation slowed down gradually over millions of years, and this is the most likely scenario, it would be a very different story. If the Earth slowed down to one rotation every year, called synchronous rotation, every area on Earth would be in either sunlight or darkness for one year. This would be similar to what the Moon goes through where for two weeks the front side of the Moon is illuminated by the Sun followed by the front side being in darkness for two weeks.
If the Earth stopped rotating completely, one half the Earth would be in daylight for half the year while the other side would be in darkness. The second half of the year it would be reversed. Temperature variations would be far more extreme then they are now. The temperature gradient would affect the wind circulation also. Air would move from the equator to the poles rather then in wind systems parallel to the equator as they are now.
Even stranger would be the change in the Sun's position in the sky. In the above scenario, Sun would just have a seasonal motion up and down the sky towards the south due to the orbit of the Earth and its axial tilt. You would see the elevation of the Sun increase or decrease in the sky just as we now see the elevation of the Sun change from a single point on the Earth due to the Earth's daily rotation.
As an example, say we live at 30 degrees North latitude. In the Summer, at a longitude where the Sun was exactly overhead, it would slide gradually to the horizon as Fall approached, but since the Sun has moved 90 degrees in its orbit, it would now be due west. As Winter approached, you would now be located on the dark side of the Earth. You would have to move to a longitude 180 degrees around the Earth to see the Sun 1/2 way up the sky because in the Winter, the Sun is 50 degrees south of its summer location in the sky.
There would be other effects of the Earth's rotation slowing also. The magnetic field of the Earth is generated by a dynamo effect that involves its rotation. If the Earth stopped rotating, the magnetic field would no longer be regenerated and it would decay away to some low, residual value due to the very small component which is 'fossilized' in its iron-rich rocks.
There would be no more 'northern lights' and the Van Allen radiation belts would probably vanish, as would our protection from cosmic rays and other high-energy particles. Losing this protection would cause serious health issues.
Be glad for our Earthly rotation, without it we would be much worse off!

If the earth immediately stopped rotating, then inertia would wreak havoc. The earth is rotating at about 1000 mph (25,000 mile circumference, rotates in 24 hours). Imagine what would happen if you were instantaneously accelerated to 1000 mph.
If the earth *slowly* decelerated, then it would eventually stop with one side facing the sun (similar to the way the moon always has the same face toward the earth). This would mean one side would be incredibly hot, and the other extremely cold. The only easily habitable place would be on the edge between sunlight and darkness.
For preparation, there's not much we could do except try to develop habitats for living in the fringe area, or travelling to a more hospitable planet or moon.

a couple of options include going to the moon or live in space stations.
Now what we could do in preparation is to place all our provisions along the equator.
when the earth stops. Everything will be flung off at a tangent real fast including the sea.
Now if we are on the moon, and with a bit of luck. We can have some stuff, including water transported. Free energy.
Now this is the best part. the earth has stopped rotating and so has the moon. so we can now build a lift between the earth and the moon and come back.
voila

If the Earth were ever to stop rotating, you should do the
following things:
1. Break out your very warmest clothes and store them all
together on one side of your room for use on 187 1/2 previous
days long nights. Extreme cold will occur on those long dark
periods. And, naturally, extreme heat and drought will occur
following that for 187 1/2 of our previous days length.
2. Bottle as much fresh water as you possibly can, and store
it is a protected place. There will not be normal rainfall as
we had before.
3. Get everyone in your town to face West and begin running. All of that activity might help a teeny little bit in getting the Earth
rotating East once more. you could be team leader on this
great project.
4. Study maps and locate the nearest big cave deep in the mountains. That will be your best home over the coming months of long darkness and the high heat of long day time. The length of time that this new day and night thing will last equals more than your lifetime so you can forget about it ever ending.
5. You will need to collect and store in a safe place as many MRE's as you possibly can. Use every dollar you have and borrow more to purchase these ready to eat meals. There will be no regular sources of food during the new events. Place hard candy in tins and store that away for a quick energy source also.
6. Have you seen those calume light sticks? You will need thousands of those until you learn to see in the dark. So you
should plan to purchase and store a bunch of them also. They
don't require batteries, and have an undetermined shelf life.
7. Heat packs... There will be a definite lack of heat over the long frigid night. So, you are going to need a simple source of heat.
What ever that source is, it cannot be a plug-in device that uses commercial power because most commercial power will cease to function unless it is driven by nuclear power. I think we can assume that all commercial power will stop. So, I am thinking that you might want to invest in these little heat packs that are
readily available at sporting goods stores...maybe buy them by the case and store them away.
8 Finaly, if you want to prevent all of this from happening,
vote for Hillary Clinton in the next US Presidential Election.
She can talk the spots off of a leopard, and the warts off of
a frog, so she can probably talk someone out of letting
this disaster happen. Maybe all the Democrats can vote
against the Global Disaster Plan, or unite against funding it.

The earth is never going to stop rotating -- you don't have to worry about it. Do you realize how much mass the earth has, and how much kinetic energy it has because of that mass? It would take an enormous amount of force to stop the earth from rotating. It's not going to happen.
And even if it did, you couldn't do anything to prepare, and nobody's going to go flying off or anything. All that would happen is our "day" would get longer, and parts of the earth would get really hot (pointing towards the sun), while parts would get really cold (pointing away from the sun). But which part was which would change as we orbited the sun.
What on earth (pun intended) caused you to start worrying about this so much all of a sudden?

If the Earth ever stopped rotating, there would be nothing you could do. You would die. The Earth's rotation is essential for keeping a liquid iron core and it is responsible for generating the electromagnetic field which shields us from the solar wind produced by the sun. If the Earth stopped, we would loose that shield, the planet would heat up and fry, and we would die long before the oceans would boil completely away.
In the overall picture of space and time, humanity is very very fragile and we are always at its mercy.
I have included a link which talks more about the electromagnetic shield which protects us.
Enjoy!

the present rotation era of the Earth is approximately 0.001 seconds longer than 200 years in the past. in case you employ that parent to calculate how lots longer the day would be in 5 billion years while the sunlight expands right into a pink vast, you arrive at a parent of 25,000 seconds, that's approximately 7 hours. the fee of deceleration is predicted to strengthen, although, so as that over-simplified calculation is a important decrease than-estimate. capability is being handed from the Earth to the Moon as they circulate in the direction of a situation the place they rotate with one facet of the Earth continuously dealing with the Moon. The capability is often there, so there'll continuously be rotation, however the upward thrust of the sunlight is in risk of happen in the previous this tidal locking. Your fact that the day became 24 hours long 200 years in the past is genuine. The definition of the 2d is in line with observations created from the action of the Earth between 1750 and 1890 and the propose fee from those outcomes corresponds to a date of around 1820.

Earth's rotation IS slowing but it will take millions of years to slow considerably, it will never stop entirely. I recently read that the rotation will slow to about a 47 day cycle. Don't worry about the rotation stopping suddenly it won't happen but if it did you still wouldnt have to worry about it because we would all be dead in seconds. Everything would suddenly move to the east at about 600 miles per hour!

If the earth stops rotating (by the way it eventually will but not in your lifetime) every living thing on the planet is toast. One side will be freezing and the other side will be a oven.
Actually the most probable course of action is to elect President Bush Dictator and he will destroy the Earth long before then.

depending on which side of the earth it stopped rotating, we should be prepared for half the earth to be very cold, and one side would be hotter than Hawaii. some places might be shifted, because if the earth suddenly stopped spinning, then it might shift all the continents move a little bit to one side.
