minus-squareJerb322@lemmy.worldlinkfedilinkarrow-up2·5 days agoHow far did it travel in that 2 seconds?
minus-squareRoyy@lemmy.worldlinkfedilinkarrow-up3·5 days agoIf acceleration were constant (and my math is right), it would be 194m. We can assume due to air resistance being proportional to the square of the speed that acceleration will be more initially and less later, so realistically it will be >194m
