Homework Statement


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]

Homework Equations




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."
