PhysX3.4-Some questions about collision callback

Hello, everyone, my requirement is: there is a dynamic ball in the scene, an approximate plane composed of several smaller static balls, and the dynamic ball rolls on this approximate plane.
When the dynamic ball rolls, I hope to get the static ball ID of each collision and the dynamic ball speed after each collision. Is it possible to achieve this requirement in PhysX? I am a student and new to PhysX, and I need to achieve this requirement as soon as possible, so I cannot learn PhysX systematically. I hope to get your help, thank you!
