Could someone perhaps guide me in the right direction to figure out a way to start this code?

(Assignment) "Your program should also have a feature that predicts the velocities and elevation angles at which the projectile can be launched to hit a target given a specified distance. The input to this part of the program should be only the target distance. The output from this part of the program should be the velocities and launch angles for the projectile."
I don't see a way to get both those outputs by just inputting a distance. I'm not asking for someone to give me a code, but just a something to help me start.

In this case there would be multiple velocity and launch angles. The formulae for projectile distance is
where v is initial velocity, g gravitational acceleration and theta is projection angle.
Now if d is given, then relation between v and theta will be,
Now, you can vary the theta from 1 to 90 degree in specific interval (e.g. 1 degree)and get corresponding velocities v and out the angle and their corresponding velocities in a table format.
