Figure shows two equal masses of 0.6 kg glued to each other and connected to a spring of spring constant k = 240 N/m. The masses, which rest on a frictionless horizontal surface, are displaced 0.6 m from their equilibrium position and released. Before being released, a few drops of solvent are deposited on the glue.

(a) Find the frequency of vibration and total energy of the vibrating system before the glue has dissolved.

(b) Find the frequency, amplitude of vibration, and energy of the vibrating system if the glue dissolves when the spring is (1) at maximum compression and (2) at maximum extension.
