Use a block-and-spring model like that shown in Fig. 14a but suspended from a vertical position and subjected to a periodic support displacement of δ = δ₀ cos ω₀t determine the equation of motion for the system, and obtain its general solution. Define the displacement y measured from the static equilibrium position of the block when t = 0.
