Solving spring mass damper system with Simulink?

[Slothy]

I have to solve this equation using simulink

d^2x/dt^2 + 2zw (dx/dt) + w^2(x) = F

I was using this to help me

Was wondering if this was the correct method of thinking?

Thank you

An even easier representation is to use the State Space block with A = [0, 1; -w^2, -2*z*w] and B = [0;1]. If you want to look at the position x with respect to time, C = [1,0]; if you want to look at velocity with respect to time, C = [0, 1]. D = 0 no matter what output variable whose dynamics you want.
