Hello Dr. Sassi,
First of all, thank you so much for taking a moment to answer my question.
My main problem is how to start with an explosion so that the particular can then be positioned and stopped (I'm achieving braking with friction).

I'm trying to create a particle system like the one in the image, but I can't quite get the look right. I'm trying to do it with Matrix and Shade Effector, with different levels, but I can't seem to get it right. Does anyone know how to do it correctly?
The animation is from this video https://youtu.be/9TLNDJH9E98?si=ShN-pHyhsoPpn766 minute 1:12.

Thanks for a lot
