Thanks so much for your help. I think I got it!

I am also wondering whether I should use the x1= Acoswt and x2 = Bcoswt as a substitutions or if they are specific solutions to the differential eqns.

I tried two different ways...I attempted to turn the system into an electrical circuit equivalent and I tried with free body diagrams and the following equations: mX=mg + k1x1 + k2x2 - Fcoswt mX=mg + Fcoswt - k1x1 - k2x2 (For these two eqns. the X means X double dot indicating acceleration)...

Homework Statement Consider a system consisting of two springs suspended from the ceiling. The first has a spring constant k-1, the second k-2. They are connected by a mass m and the second spring also has a mass m connected at the bottom. A periodic force is applied to the upper mass. What is...
