It accelerates more or less at the same rate at first, but gains speed quicker because the Earth is accelerating up towards the massive moon but not the balloon moon. Now we let go of something the mass of the moon (and stronger to avoid Roche effects) from the same altitude and it will hit the ground in significantly less time. We let go of it and time how long it takes to hit. We have a controlled Earth (not spinning, a perfect sphere, no air) all alone in space (so the sun isn't accelerating it for instance) and I have a stationary moon-size rigid balloon at the same altitude as the orbit of the moon. Assume m2 masses a significant percentage of Earth, like the moon say. OK, since we're getting picking about details, if you do the computation to enough significant digits, a dense object will fall faster as will a more massive hinted at this.
