Consider the system below of two coupled masses of mass M, connected to each other and to fixed supports via three springs with spring constants k.
a) Write down a pair of ODEs describing the motion of this system.
b) Solve this system analytically for the displacements x_(1) and x_(2), assuming the masses are initially at rest and displaced by amounts u_(1) and u_(2).
[Hint: Use the variable substitutions y_(1)=x_(1)+x_(2),y_(2)=x_(1)-x_(2) ].
