This question already has an answer here:

I'm trying to calculate the force of a man falling from a bridge into water below. Thus far I've calculated everything except for the force he would experience hitting the water. Would I need to do some estimation to figure it out or what? I'm a little confused with where to go from here.

The final velocity of the body would be 40.07 m/s and the mass of the body is 78 kg. I imagine that's all you would need to be able to find the force since I calculated everything else already.

  • $\begingroup$ That force would depend a lot on how the body impacts the water. A good diver would enter the water like a javelin and experience much less force than a body falling flat onto the water surface. $\endgroup$ – Gert Feb 19 '16 at 3:01

  • $\begingroup$ All that said there simply isn't a simple answer to this question at modest speeds. It ends up depending on the shape, density, malleability of the impactor as well as depending strongly on the speed itself. $\endgroup$ – dmckee Feb 19 '16 at 3:06
  • $\begingroup$ Sorry I wasn't aware that you could edit the question and it would bump it to the top, I figured it would be okay to repost because I think I worded the question badly the last time and people thought I meant something else because I confused them. Sorry! $\endgroup$ – user108559 Feb 19 '16 at 3:21
