In principle, the rotation of the Earth could reverse by the intervention of an outside force, e.g. collision with some moving object of comparable size. No such object is known (planetary motion is constrained), and any such collision is likely to break up the Earth. Otherwise, it would take a miracle to stop the rotation

I suspect that it would cause a huge problem with time relative to the position of the sun or moon. The two would be out of sync and all of technology that relies on timekeeping would have to eventually be reset to the "new time". Imagine if the Earth stopped rotating at 9:00 after it just turned dark and began its reverse spin. It may take who knows how long to get to a full-speed spin again. So the moon could be suspended in place for awhile. The sun would begin to rise in the West and set in the East.
This is assuming a supernatural reversal of the spin of the Earth. More likely to happen would be a giant collision with a huge asteroid in which case, we would all be dead from the impact.

In order to stop such a massive object from spinning in one direction and accelerate it the other way, an incredebile amount of energy would be expended. That energy would be equivalent to 10^14 megaton of TNT, that is 200000 tonnes of TNT for every square metre on the surface of the planet, oceans included.
So, what would happen if you had the energy equivalent of 200000 tonnes of TNT exploding simultaneously every square metre on the planet to reverse the rotation of the planet? Think that would mess up pretty much everything totally?

really rotating or accelerating bodies do (or might want to) impression the gravitational field in that section, in a phenomenon regular as body-dragging, or the Lense-Thirring outcome. I say "might want to" because so a thoughts as i'm conscious there is not conclusive info that this phenomenon exists (by using that is impacts being so small), besides the indisputable fact that it really is anticipated through the final theory of Relativity and analyze of satellites do element out that the outcome is there (yet favor confirming). Reversing the direction of the earths rotation might want to opposite this body-shifting outcome, yet this may be absolutlely undetectable to us human beings without fairly precise measuring kit.

The sun would rise in the west, and set in the east, but other things would change too. If the Earth spun at exactly the same rate in the opposite direction, the average day would be 23 hours, 52 minutes and 9ish seconds long, and there would be 367.242 days in a year instead of 365.242 days.

I would imagine that since the many layers and plates that make up our planet are shifting at different speeds and directions, a sudden change such as rotation direction (which is just about impossible) would cause earthquakes, tidal waves and much much more. We wouldn't survive it.

we will be ejected from earth because some stupid newton's law when it stops to go backwards, so it wouldn't matter because we all be death

The water in my toilet would spin the other way when it goes down!
