No rocket going into space leaves the ground at 25,000 mph.

Escape velocity is just the theoretical speed at which an object would need to instantaneously accelerate to in order to escape gravity without any additional energy. It is not the speed required to get into space.

And in this case, where the earth stops instantly, then the effect on "flinging you forward" is instant, which is instant acceleration, or as close as you're going to get. So, no, 1000 Mph is not enough, right?
