Mechanics Thing(algebra craziness)

  1. Mar 14, 2008 #1
    1. The problem statement, all variables and given/known data
    The task is to consolidate the three equations used to calculate the distance that a projectile fired at an angle and at a height above the ground will travel. Its an experiment with an adjustable projectile launcher. Calculate the velocity using conservation of energy based on the height straight up that the projectile reaches.

    2. Relevant equations

    V=rad(2gh), Dy=.5*a*t^2, Dx=vx*t

    3. The attempt at a solution

    All attempts at consolidating this into one step have result in enormous ridiculous fractions that are very difficult to simplify. Things like v^4*cos^2(theta)*sin(theta) and large radical expressions. Any help wpuld be greatly appreciated!
