Hmmm... Well you could figure it out with the same kind of formula...

If the end result is HIGHER than the diameter of the earth, then take away the diameter from the result and thats how far above your original starting point you'd be..

The interesting thing is that if that did happen, theoretically your swings would get bigger and bigger each time due to the acceleration... You might even break free of the gravitational pull if you did it for long enough...

So thats the main thing, is it less than or more than the diameter.
