Homework Help: Energy produced by oxygen molecule vibrating

  1. Dec 29, 2009 #1
    1. The problem statement, all variables and given/known data

    An oxygen molecule vibrates so that the distance between its intramolecular bonds changes from 1 Angstrom to 3 Angstrom. This change occurs 1000 times every second. If the average speed of the movement is 100 m/s, and the weight of the molecule is 10^-26 kg, how much energy is produced by these vibrations?


    2. Relevant equations
    KE=1/2mv^2


    3. The attempt at a solution
    KE= 1/2 x 10^-27 kg x 100m/s^2
    = 5 x 10^-25 Joules ? (This is not correct, the answer is 1 x 10^-22 Joules)
