Homework Statement
The system is this:
I want to find the equation describing it. Assuming K = K and M = M, no friction.
Homework Equations
Nothing to post here.
The Attempt at a Solution
For left M: ##f(t) = Kx_1 + b \frac {d(x_1 -x_2)}{dt} + M \frac {d^2 x_1}{dt^2}##
For right M: ## b \frac {d(x_1 -x_2)}{dt} = K x_2 + M \frac {d^2 x_2}{dt^2} ##
Adding the equations: ##f(t) = Kx_1 +K x_2 + M \frac {d^2 x_2}{dt^2} + M \frac {d^2 x_1}{dt^2}##
Is that the way to go here? I have no background in physics, this popped out in a homework question. Please let me know if I am on the right track.
