Physics/Math Question

  1. Jun 20, 2007 #1
    1. The problem statement, all variables and given/known data
    Given: W = J/s, J = Nm, N = kgm/s2, Hz = 1/s
    Convert W²/NJHZt to mks and simplify. Make sure to list every step.

    3. The attempt at a solution

    I am completly lost...:S

    Just plug those values into the expression and cancel everything that can be canceled.

    [tex] \frac{W^2}{NJHz}
    = \frac{(\frac{J}{s})^2}{NJ\frac{1}{s}}
    = \frac{\frac{J}{s}}{N}
    = \frac{Nm}{Ns}
    = \frac{m}{s}
    [/tex]

    is this right?
