Need an equation for artillery

  1. Jul 18, 2014 #1
    Hi everyone! I am looking for an equation for a projectile which takes into account air resistance. I preferably want 1 equation, which can output the desired elevation. I have the initial velocity, range and change in elevation.

    I have this http://en.wikipedia.org/wiki/Trajectory_of_a_projectile#Angle_required_to_hit_coordinate_.28x.2Cy.29

    And was wondering if it could be modified to account for air resistance?

    Not in a general way. Air resistance can be complicated, and it makes the nice two (both coordinates) linear, independent equations for a free fall non-linear and coupled.
    A numerical simulation of the path is a common way to predict a trajectory.

    So how could I do it?

    Numerical simulations? There are tons of books and internet pages explaining various methods.
