p0tr7y (k f:hy of spring constant k are connected as shown to a mass M in equilibrium. The horizontal platform shown between the springs and the springs themselves have no mass. If the mass M is slightly displaced vertically, the mass exhibits simple harmonic oscillation. Assume that the horizontal platform does not rotate during the o
