Graphing Trajectory with Drag using Program

  1. Feb 14, 2014 #1
    1. The problem statement, all variables and given/known data


    mass = 100 Kg
    Cross Area = 4
    Drag = .4
    Initial velocity = 17.59 m/s
    Gravity = 9.81
    Angle Changes according to the position of the mouse
    Terminal velocity = 31.649 ; Don't know if its relevant but I calculated this


    2. Relevant equations


    Y1 := X*tan(ang)-9.81*(X^2)/(2*((Vel*cos(ang))^2)) ; This is the equation without drag


    3. The attempt at a solution


    I have looked up everywhere for Drag equations, but I can't find an equation

    That solves for the height Y at intervals of X
    That has all the variables I have anything not listed isn't relevant or shouldn't be
    Everything is constant


    If there is anybody able to help me I will be forever grateful
    I have been working on this for months, trying to figure this out, and have wondered why is wasn't working when finally found out there's drag in a simple game which turned out not to be so simple.

    If there is anything that I can help with I will most gladly try and help.

    Thank you for your time I really appreciate it.
