Essay
The total energy of a water molecule in the ground state is 9.2 × 10-20 J. Find the amplitude and maximal velocity of vibration of a hydrogen atom. Compare the amplitude to the length of the O-H bond (9.6 × 10-11 m). The mass of a hydrogen atom is m = 1.67 × 10-27 kg. The spring constant for the H-O bond is k = 780 N/m.
