Reversing the rotation of the Earth, effects

So, in the first episode of "Phineas and Ferb", the evil Dr. Doofenshmirtz tries to reverse the rotation of the earth. His plan fails in show, and there are several reasons why his plan would have never worked. But, it got me wondering, what would happen if you could reverse the rotation of the earth?

We can probably assume that Dr. Doofenshmirtz wanted this to happen quickly, within a day, so from normal rotation speed to reverse rotation within 24 hours. We can also probably assume that he wanted to get to the same speed in reverse, so from $460 \ m/s$ or $1000 \ mph$, in our current direction, to zero, to $460 \ m/s$ or $1000 \ mph$ in the other direction all within 24 hours.

My first thoughts is that this would be very apocalyptic, my second thoughts were that the forces necessary would tear the earth apart. I am asking for a description of either what would happen on earth, or a confirmation that the planet would be torn apart.

Addendum to original question. In the show itself, Doofenshmirtz essentially tries to reverse the rotation of the earth by yanking on the eastern seaboard of the United States. If one could "yank" on the entire eastern seaboard with an even force, what would happen then?
