Homework Help: Help with units

  1. Apr 9, 2005 #1
    i just need help with finding the units to a physics problem at the end. some examples...


    [tex]\sqrt{\frac{940N/m}{0.038kg}}*(0.25m)[/tex]

    it comes out to 39m/s.

    i know that since it's velocity, it should always be m/s. but there are some question that i dont really know what the final units should be.

    without the numbers...
    [tex]\sqrt{\frac{N/m}{kg}}*(m)[/tex]
    it doesnt seem like anything can be canceled out because the units are being sqrtrooted.

    Put newtons in base units, N = kg m s^-2 and you'll see everything inside the square root cancels out, besides the s^-2.
