(62,444 posts)Again, I probably took more physics than you did, and one of the things I learned is that guessing at things is a poor substitute for actually relevant figures and/or experiments.
Dealing with impact forces is a little more difficult than people with some introductory physics normally assume.
You might think, that if you legs normally hold up your weight, that somehow that's the usual amount of force your legs can transmit, but that's simply not how it works.
If you weigh around, say, 150 pounds, then your legs can transmit impact forces many times that amount. Otherwise you couldn't, say, jump from a height of a couple of feet onto a hard surface.
Saying "I think I know the answer" without reference to anything physically relevant, is the precise opposite of what Mythbusters is about.
