Have a Ball travel in a nice arc to a specific location from anywhere

Hi All,

I am trying to figure out a way to essentially simulate the setting in volleyball but very simple to use.

^ Above is a poorly drawn example of what I am trying to accomplish where the orange lines are the example trajectory of the ball. I can hardcode the location where the ball is needing to go but I just need to get it there.

Where there are about 3 key locations the ball needs to be put to in an arc when traveling there. I am assuming you might be able to do this with Splines by having the end of the spline stay static but assigning the start to wherever the ball is maybe?

Anything is welcome!
Thanks
