If i have a string which i pull and extend beyond it's antural length and then let go, what will the enrgy composition be like when the string first becomes slack? Would it be Gravitational PE and Kinetic Energy? For example when it is extended all the nergy is elastic potential, but when it is let go for when it first becomes slack does it become a mixture of kinetic energy and GPE, i thought because if the string is slack there'd be no extension or Elastic Potential. Also for the GPE what would the value of h be in mgh? would it be the natural length?
btw sting is connected at one end at the ceiling and the other end to a mass
