Ummm... no? It'll come out at roughly the same speed (less if the moment it came out there was still energy trapped in the form of compressed marbles when it emerges). Why would it be otherwise?
- Retric 15y agoHave you ever seen those desktop toy's where steel balls 10+ steel balls are strung up next to each other. You drop one and it fall hit's one end of the chain and in less time than it would have taken the first ball to move that distance the last one pops off the end? Same concept the final ball moves a little slower than the first ball that hit the chain, but it start moving sooner than it would have taken the first ball to move the distance of the chain.
- maaku 15y agoOk that's true, but not how I read your post. Yes the energy is transfered at the speed of sound in the material, but I read your post as saying the velocity of the marble on the end is greater than the velocity of any other marble, including the one you push in, which is certainly not true.
