Is it easier to stop a sports car going 75mph or a bus going 55mph.
Love this type of "anology"
The bus weighs at least 10 times as much as the sports car.
For the bus/sports car thing to have any meaning, you would have to be comparing
a 300 gr arrow to a 3000 plus gr one. Be interesting to hear what FPS your bow gets with a 3000 gr arrow
and what the trajectory difference would be.
