Distance Matching Locomotion : Giving it a shot!

I’m trying to calculate the stop distance in Blueprint. The physics calculations should be straightforward, but I don’t quite understand what the Ground Friction and Braking Friction Factor are in the Character Movement Component. In physics speak, I need the normal force, coefficient of friction, initial speed, etc. I’ve never tried to do these simple calculations in BP, so I have a few questions I would appreciate help on:

1.) Where exactly do the Ground Friction and Braking Friction Factor fit into a physics calculation?

2.) Is there a character mass somewhere in BP?

Or perhaps I’m approaching the calculation in completely the wrong way…
