A particle of mass m attached to a rigid support by a support of constant k. At equilibrium, the spring hangs vertically. This mass-spring system is joined by another identical oscillator, whose spring is hung from the previous mass. Consider only the vertical movement.

a)  write the equations of motion of the coupled system

b)Compute the normal mode frequencies for one-dimensional vertical oscillations and then show that the ratio of the two normal frequencies is √5+1/√5−1

c)Find the ratio of the amplitudes of the two masses in each separate mode.

(You do not need to consider the force of gravity acting on the masses because it is independent of the displacements.)
