Ball is not deaccelerating

[FelipeMartins96]

Describe the bug

• The ball is not reducing its speed when unbothered

To Reproduce

• Position the ball outside the field
• Give it an initial velocity
• Watch as it moves until the horizon

Expected behavior

• Ball should deaccelerate with friction forces

Additional context

• This grSim pull request touches on the same functions, although it seems like their ball still deaccelerates to a small velocity
• I tried implementing the same ball friction function as grSim, but I think that for it to work properly in the VSS setting, we need to calculate the ball friction with the VSS field
