spring and resistor is the same graphic lol
This.
Looks like you need to find the second order ODE based on x(t) = cos(wt + delta) where w = (k/m)^1/2... I remember doing a similar problem with masses' suspended on several springs in my DE class, I believe each spring will have it's own respective equation in terms of omega, m, and k and you'll need to set up a 3x3 matrix and apply cramers rule to solve for each variable.
