minus-squareOnomatopoeia@lemmy.cafelinkfedilinkEnglisharrow-up16·2 days agoGood approach. Start with the momentum of the rotational masses, assume no suspension (to make the math simpler). My guess, a few feet. There’s surprisingly little momentum in all those components compared to the mass of the vehicle.
