Laplace Transforms: Coupled Springs

Part 1: Laplace Transform

Problem Statement: (Equations typed out in mathcad and uploaded as images)

This is a system of two masses connected by two springs with spring constants k1 and k2. This system is shown below.

From the FBD, the equations of motion can be determined to be as follows:

To solve the system let K1=6 k2=4, m1=1, m2=1 and x1(0)=0, x1'(0)=1 x2(0)=0, x2'(0)=-2
