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...


    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...
    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.
