I fell 17 feet off of a roof. How fast was I traveling when I hit the ground?

Question

Broke my back in three places just wondering my speed when I hit.

Answer 1

It depends of your weight. I know there's a formula of physics for that, but I don't remember how it worked.  

Answer 2

between 11 and 12 mph?

Answer 3

Around 10 m/s (~22.5 mph).

Answer 4

well, gravitational acceleration is 9.8m/s/s...

9.8 meters is about 33 feet, so less than 33 feet per second... perhaps

Answer 5

At the time of impact your speed reduced to 0. Sorry I couldn't resist.

Answer 6

i cant estimate

so you'll have to set up a proportion

fall or get some1 to fall 5 feet(lets say they were going 2mph)

so 17 over X equals 5 over 2

5X = 34

X = 6.8

so from that you *possibly* travled 6.8mph...  

Answer 7

I would say that it is closer to 14 to 16 mph.

Answer 8

The speed coming down doesn't really matter as much as the stopping at the bottom.  

Hope you make a speedy recovery.

Answer 9

5 mph
