Problem with Units

  1. Mar 18, 2009 #1
    1. The problem statement, all variables and given/known data
    In a problem to determine the maximum elastic potential energy of a molecule, I have the following equation:

    [tex] A= \sqrt{\frac{6.626*10^-34 Js}{2\pi}}\times(\frac{1}{(1.14*10^-26kg)(1.85*10^3N/m})^(1/4)[/tex]

    2. Relevant equations


    3. The attempt at a solution

    The answer is [tex]4.79*10^-12 m[/tex]

    I have tried to coax the definition of the Joule and Newton units to come out with an answer in meter; however I do not see how this can be made to work.

    Thank you for your kind assistance

    (J*s)1/2 = kg1/2*m*s-1/2

    (N/m)-1/4 = kg-1/4*m-1/4*s1/2*m1/4

    And there hiding in the denominator - the extra kg-1/4

    As they say in poker "Pot's right."
