# Impact force estimate
# Scope: Energy-equivalent average stopping force; peak force is not predicted.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

mass = 1 kg
speed = 2 m/s
stoppingDistance = 5 mm

energy := mass*speed^2/2 [J]
averageForce := energy/stoppingDistance [N]

check average force budget: averageForce <= 500 N

scenario alternative: mass = 0.8 kg
