Problem

Two identical masses are attached to separate horizontal springs. Spring X has constant

k

, and the mass oscillates with amplitude

0.60\,\text{m}

. Spring Y has constant

2k

, and the mass oscillates with amplitude

0.30\,\text{m}

. Calculate the ratio

E_Y/E_X

of their total mechanical energies.
