Dear Mike,

I hope you're alright! Well, neglecting air resistance and assuming you didn't leap up (or down) and simply fell, you were going about 44 ft/s or 30 miles an hour when you hit the ground. The fact that you landed on your feet probably helped by slowing the fall a little bit before the rest of you hit the ground. Ouch.

Hope that answers your question!
