Homework Help: Powers of p and q from a=v^p*t^q

  1. Sep 2, 2012 #1
    How do I go about solving for the powers of p and q to make the equation dimensionally consistent?

    Any help or advice would be much appreciated! :smile:

    I'm assuming v is velocity, t is time and a is acceleration?

    Acceleration has units of m/s2, while velocity has units of m/s. So the only valid values of p and q would have to be p = 1 and q = -1.

    Yes, I failed to mention that. Thank you for your help. :smile:
