130. The spring is relaxed at y = 0, so the elastic potential energy (Eq. 8-11) is Uk y el = 1 2 2 . The total energy is conserved, and is zero (determined by evaluating it at its initial position). We note that U is the same as Δ U in these manipulations. Thus, we have 0 =+ + ¡ =− KU U K U U ge where U g = mgy
