Homework Help: Dimensional Consistency

  1. Aug 26, 2010 #1
    Acceleration is related to velocity and time by the following expression: A=V^p t^q

    Find the powers p and q that make this equation dimensionally consistent.

    You know that acceleration is L^1 T^-2, that velocity is L^1 T^-1 and t is of course T.

    [tex]V^p t^q = (L^1 T^{-1})^p (T)^q = (L^1 T^{-2}) = A[/tex]

    this is your very basic dimensionality problem. Try to look over some examples and post your work if you need further help.
