Chapter 9, Problem 19P

Three masses are suspended vertically by a series of identical springs where mass 1 is at the top and mass 3 is at the bottom. If $g=9.81\text{m}/{\text{s}}^2,m_1=2\text{kg,}{m}_2=3\text{kg,}{m}_3=2.5\text{ kg, and the }k\text{'}\text{s}=10\text{kg}/{\text{s}}^2,$ solve for the displacements x,
