发帖数: 248 | 6 It is not fair to compare the average 100m speed of a 4x100m relay to an
individual performance, as the start-up time saved on the 2nd through the
4th athletes have to be taken into account. |

is normally less than 0.2s; The average is then less than 9.46s? |

发帖数: 248 | 12 There is also a little overlap between the prior and the following athletes
that allows the next athlete to accelerate to a certain speed.
In other words, if you look at the v-t profile, except the first one, there
is no lag due to start-up reaction and the speed does not drop to 0.
