Hi, so i'm trying to make a code which will be used in a uni project. Basically, I need to code something which calculates the angle I need to fire a ball at to get it through a target. For the purposes of this, velocity, target distance in x direction and y direction are fixed. 36.5m/s, 6m and 1.14m. I cannot for the life of me work out how I can do this? I've tried loads of different for loops, itterating through a linspace of all possible angles but nothing works. The angles are always way too tiny. Any help would be super apreciated.

PS. (I am using normal drag equations, F = 1/2 rho v2 A C.)
