I obtained lift and drag forces for an object I was testing in a wind tunnel and I wanted to know if it was possible to do a projectile motion problem with the following variables;
I know the initial velocity of the object, V=76m/s, the possible launch angles = 30, 45, or 60 degrees, and gravity = 9.81m/s^2.
-I also have tabulated data of the lift and drag forces on the object at 3 different wind speeds (80, 130, 170 mph) while varying the angle of attack (AOA) from -10 to 30 degrees.
I took the three drag values at 0 degrees AOA and found a linear relationship between the wind speed and drag values. I used that relationship and subtracted drag off of the ideal equations of distance and height of projectile motion and the values I got don't make sense. Is there another way I can do this or am I missing some important information to solve this problem
