how much does a falling object "weights"? Hi ev. the other day i was asked by a friend that does "aerial silk" (http://en.wikipedia.org/wiki/Aerial_silk, just found out it was called that :P) how much (still) weight should the beam (to which the silk is tied) hold in order to hold her weight after falling say, h meters.. i started thinking about it, thinking it would be easy, but i'm not sure how to approach it. I mean, i can get the energy that needs to be lost (mgh), but i'm not sure how to "spread it around" in a way that won't make me say 'sure, go ahead' and then end up bringing flowers to the hospital Is there another way to approach this problem? what do i need to figure out to "spread around" correctly the energy lost? I guess this is more of an engineering question, please move the thread at will.. pd: this is my first post so i should mention. i'm not a native english speaker, i hope that you will learn to forgive the way i get around to say things which can get strange sometimes.. no grammar nazis around?
