Bouncing Ball

So to start again this new season I will work again on the bouncing ball. I notice that there is a lot of thing off in this animation, I opened it again but I was not able to solve it so I did some search. I hope this will help me!

On this website I find a chart that show the bounciness of different type of ball.
