I don't understand where the 3.6 came from. I used the equation given for height, i am not aware of the physics used in your code. Could you tell me how you derived your equation?

need guidance if any can be given. When i return a vector with the last value of 0 it does not seem to return that value, if i increase the size of the vector, the 0 is there. for example returning ret: [1,2,0] only shows [1,2]. but if i increase the vector size by one it'll return [1,2,0,4]. i don't understand why it's not recognizing the 0 when it's the last value
