I’ve made a small calculator in Desmos, to calculate the angle [deg] and exit velocity [m/s] needed to hit the middle of the upper hub from a specified distance [m] , height [m] and angle [degrees].

“a”: shooting angle needed.

“v”: exit velocity needed.

“S”: the angle you want to hit the target in.

“d”: specified distance between the shooter and the middle of the upper hub at any time.

“H”: height difference between the shooter and the upper hub.
