puck_mu_from_decel — DRIVE puck op

• Data kinds: signal × matrix → table

• Call: import fullseye as fs; fs.ledger.puck_mu_from_decel(t, xy, g: 'float' = 9.81) -> 'dict' (to call the implementation directly, import puck; puck.puck_mu_from_decel(t, xy, g: 'float' = 9.81) -> 'dict'; from the registry, opsdrive.get("puck_mu_from_decel"))

Usage

Fits a quadratic to the distance s(t) along the direction and obtains μ = −a/g from a = 2c₂ (Coulomb uniform deceleration). {"mu", "a", "v0", "resid_rms"}. N < 4 raises ValueError.
