Hi, I'm a mechanical engineer from Norway who has an work related query. Please see the attached picture describing the problem. I'm trying to figure out how heigh mass 1 travels if mass 2 is quick released when being suspended in a spring. I'm also trying to figure out a the maximum acceleration, but thats 2. priority. I have tried to work out an answer my self, but I don't think it's correct. The thing I can't get my head around is how to calculate the height mass 1 travels above it's equilibrium due to the speed and spring tension. If the mass 2 had been release slowly, the answer could easily be found using the energy forumula(E=1/2*k*x^2), as far as I can understand. Any bright minds who could spare a few minutes explaining me this? Help is much appreciated! Have a nice sunday.
