13. One track event is the 4 x 100-m relay in which
each athlete runs 100 m and
passes a baton (stick) to the
next runner who then runs
100 m, and so on for a total
of four runners. The runners
receiving the baton can start
moving before they receive
the baton. They must have
the baton in their hand when
they begin their 100-m run.
The average speed of the
400-m relay is less than the
average speed for a 100-m
sprint. In the 100-m sprint,
the runner begins from a
stopped position in starting
blocks. Use what you know
about acceleration, average
speed, and running starts to
explain how this is possible.
