hey folks, I am making a program that uses object tracking to watch a juggling pattern and plays notes based on the peaks of the balls. I want to predict when/where(x,y) a peak will happen before it does and what i have to work with is when/where(x,y) the ball appears in each frame. I have looked around a bit online, but physics is so foreign to me and I am having some trouble. Here is a sample problem: FRAME #1 time = 0.00, x = 10, y = 10 FRAME #2 time = 0.05, x = 12, y = 16 I just made these figures up, but is this enough information to determine the balls trajectory? or do I need a FRAME #3? if it is enough, then what formula do I use to get the position/time of the peak? Any help whatsoever would be so greatly appreciated, let me know if this doesn't make sense and I will re-explain. Thanks!
