# Brake torque and stopping time
# Scope: Constant deceleration, no reaction delay or traction calculation.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

mass = 100 kg
speed = 5 m/s
deceleration = 2 m/s^2

distance := speed^2/(2*deceleration) [m]
force := mass*deceleration [N]
energy := mass*speed^2/2 [J]

check stopping distance budget: distance <= 8 m

scenario alternative: mass = 80 kg
