The oxygen molecule (O2)may be regarded as two massesconnected by a spring. In vibrational motion, each oxygen atomalternately approaches, then moves away from the center of mass ofthe system. If each oxygen atom of mass m=2.67 x 10-26 kg has avibrational energy of 1.6 x 10-21J and the effective springconstant is 50 N/m, then what is the amplitude of oscillation ofeach oxygen atom?
