Projectile Mechanics

  1. Oct 4, 2008 #1
    1. The problem statement, all variables and given/known data
    A project is fired from an origin that reaches a height (h) and range (R). Show y = (4h/r)x (1-x/R). Then find the distance.

    2. Relevant equations
    Any really. I was just using h(max) = v[y]t+1/2at^2, then R=v[x]t, then trying to put them both into y=mx+b... but nothing really comes of it.

    3. The attempt at a solution
    I managed to solve for V[y] to be (-gt) then for V[x] to be R/T... then I eventually worked it to y=(x/R)(h+ (v^2/4h)t^2... but can't seem to find anything for T or really get any closer...
