does the length of the arch has to be the same length througout?
Hi Riccardo,
No the width of each arc will be smaller and smaller.
A good way to think about it is that the parabola gets the bottom section chopped off of the previous parabola. This means the width is reducing each bounce.
The X location curve will be linear while it is in the air, and then instantly change speed on each contact. Like I tried to explain in the video yesterday.
Hope that helps.
