Homework Help: Dimensional Analysis Type Promblem

  1. Oct 15, 2007 #1
    Dimensional Analysis And Projectile Motion Problem

    1. physics.jpg



    The work I have shown below is my attempts at doing the steps shown to get that equation in the problem, which is what the "answer" is. I need to find the work. Am I on target?

    And I am totally clueless as to how I get the second answer. I know that [tex]\theta[/tex] would equal 45 degrees right? Optimal launch angle disregarding air resistance. But I'm not sure.
