In a relay race the acceleration zone is 10m long.
huh.......
the space on the track you gain your true speed ------------------------------------------------------------------------------------------------------------- The changeover zone is an area within each lane, 20m long, which begins at the 90m mark from the start of the previous leg and ends 110m from the same point. The baton must be exchanged within this zone. The acceleration zone begins 10m before the change over zone and ends at the start of the changeover zone. The outgoing athlete must start between the start of the acceleration zone and the end of the changeover zone (a length of 30m). The baton is not allowed to be exchanged within the acceleration zone The purpose of the acceleration zone is to allow the outgoing athlete to reach close to top speed as the baton is exchanged. This is good as it is the speed of the baton that is important.
The acceleration zone is the portion of the runup area for the pole vault, long jump, etc. where the athlete starts his run and gets up to speed.
The exchange zone on a 400 meter track is 20 meters long. For races involving 200 meter legs or less, a 10 meter acceleration zone may be marked on the track and used by the runner receiving the baton to accelerate to match speed with the incoming runner. With or without an acceleration zone, the baton must still be exchanged within the official 20 meter zone.
[acceleration] = [any unit of length] / [any unit of time]2
[any unit of length] / [any unit of time]2 is a unit of acceleration
Gravitation can be expressed as either an acceleration or a force per unit mass.[Acceleration] = [Length/Time2][Force per unit mass] = [mass-length/Time2] per [mass] = [length/time2]
It is the positive square root of its length.
The unit of acceleration is Length/Time2 .
(Any unit of length or distance) divided by (the square of any unit of time) is a unit of acceleration.
[ force ] = [ mass ] [ acceleration ] = [ mass ] [ length/time2 ] = [ mass-length-time-2 ]
The Baton Changing Zone is 20m
