Homework Statement
Ok I am working on a spreadsheet that calculates the velocity/position/drag of a point-mass projectile and I have been digging up the same equations for days and they aren't helping... lol... I just can't seem to get the numbers right, any help would be greatly appreciated :)
Homework Equations
Vx = Vx(0) + t*Ad,x(t)
Vy = Vy(0) + -9.8*t + t*Ad,y(t)
...
Fd = Drag Coefficient * Air Density * Velocity^2 (how can drag be dependent on velocity and vice versa? This causes a circular reference problem in Excel...) * Frontal Area
The Attempt at a Solution
Gah... more possibilities than exist in the seventh dimension... lol
