Cute, but momentum and kinetic energy aren't comparable.
Momentum: p = mv
Kinetic Energy: E = 1/2 mv^2
IOW E is the first integral of p with respect to velocity.
Your suggestion has something important going for it, though -- more massive vehicles would have to slow down.
- dalek_cannes 13y agoGiven one, the other is implied though. Only the limit will have to be set accordingly.
- aa0 13y agoYou're wrong. The relationship is different, the graph of the speed limit vs velocity would also be different, for the same masses/cars.
