A question for the physics folks

I gave the answer above.

Here are some calculators to help to determine.

32.2fps/ps is terminal velocity.

Not quite....32ft/sec squared is an acceleration, not a velocity. Terminal velocity is determined by the objects mass and surface area since the gravitational constant remains....well, constant.

Or here's another one.

Set it to imperial.
Enter free fall time of .36469 and it will calculate a distance of 2.1 feet and a velocity at impact of 8mph.

It really doesn't matter because any fall that spans a greater distance than your own height can be fatal. You can die falling off a step ladder, so be careful.

My great uncle died changing a light bulb. He fell off the washing machine. That is a Okie way to go...

There.

There.

Bravo! He showed his work too!

^^^ Of course, this assumes he has no velocity vector to begin with...

You could trip and hit your head on a curb and die. I've jumped out of hay lofts and not broken anything also.

I think the idea with a terminal height (not terminal velocity) is that it's a height at which there is no safe way to land. Even if you land feet first it's gonna kill you.

Falling from 6ft:

LOL!

I stated that. I think it's a valid assumption. The idea being if you fall off a ladder or such.

I agree completely. I was just saying that a lot of people do not realize that you can die from even a very short fall. People survive falling 2-3 stores all the time. I knew a guy in high school that had a black belt in ninjitsu and he would jump off the 3rd story balcony at school, land in a roll and walk away. And there are people that trip and fall off a curb and die.

My response was physics-free because I don't do math.
