The momentum of your fall would send you far up the other side, but not as far as the original point you jumped off was... Then youd get pulled back to the centre and up the original side, pulled back, up other side, constantly travelling less and less...

You could probably figure out how far each "swing" would be and how many "swings" there would be with some kind of formula...

Acceleration -
The amount of force gravity has * (velocity of you[radius of the earth/time] * your weight)

Reverse it for the deceleration, then however much the result is over the radius take that as the new distance and work out the acceleration again...

But I hate maths, so screw actually working that out and theres probably some vital thing that I missed.
