I have a roulette wheel and a ball spinning in opposite directions(adsbygoogle = window.adsbygoogle || []).push({});

First I need to know how to calculate the deceleration of the wheel if I want it to stop over a distance of 370 degrees. I have d, Vi, and Vf=0. I have this formula which seems to work but does not look right:

this.wheelDeceleration = (this.wheelInitSpeed/this.wheelStopDistance)*2;

Then I need to know how to calculate the ball's deceleration so its final velocity will be 0.2 when it reaches to winning slot. I know the distance to the winning slot, I know the velocity of the ball and the velocity of the wheel. I also know the wheel's constant deceleration (a).

The trick is the fact that the wheel is also decelerating and that's where I'm stuck.

Thanks

Philippe
