In your first thread: /forum/discussion/29933/action-reaction-force#latest I described a useful analysis to answer your question. That is a Static Structural analysis. In that analysis, an arbitrary force (say 1000 N) is applied to the face of the rubber pad and the deflection is obtained. Divide the applied force by the static deflection to get the Stiffness, K (N/m). Set the known Kinetic Energy to 1/2*K*x^2 to solve for x, the displacement at which all the Kinetic Energy has been converted to Elastic Strain Energy. Now the peak force for an elastic impact can be calculated from F = K*x.
