Very fast. Though I don't know how to calculate it since the acceleration due to gravity would decrease toward the center.
Another thing I can't really calculate is what path you would fall. It wouldn't be a straight line, at least if you were not drilling a hole down the axis of rotation since the planet spins. But if the Earth were hollow and you fell (down) off the surface your trajectory would describe the actual hole you would want to dig to get to the other side. I don't even know if it would pass through the center, due to the planet spin. But maybe Earth doesn't spin fast enough to make much difference here.

How is this. Free fall is the absence of any resistance or counter force to a body's obeying the laws of gravity. What speed would be reached as you pass the center? Anyone know?

At least it should feel like it, the same at both ends and the center. For that matter it should feel like free fall even if you were just floating motionless at the center. In all cases there is no relative acceleration pushing one part of your body into another (ignoring human size tidal stress). But maybe I misunderstand the definition of "free fall". - Tom Manfredi, Albert E wrote: > Bob Miller wrote: > > >>Theoretically the only line where you experience free >>fall is the one thru the center > > > Agreed. > > >>and you would experience it until you reached zero speed >>on the other side > > > Not "free fall" all the way through, because your acceleration is > steadily decreasing throughout the trip, going increasingly negative > (slowing you down more and more) after you go by the core.
