1. I'm currently working on a science project, and I need to know the initial velocity of a track runner. I know the formula in order to figure this out, but unfortunly you need the acceleration, which is what I'm really trying to figure out. :?

So if anyone knows how to find or figure out(without using acceleration) the initial velocity of a runner, it's greatly appreciated!

All you need to do is get the initial speed at the same point as the initial distance . Then:

a = v^2 - u^2 /2s

where
u is the initial speed
v is the delta speed + u
s is the delta distance

You're welcome.

Acceleration is just how much somethings speed changes over a given distance. So just take the first speed at the beginning of that distance and the second speed at the end of that distance and its a sinch.

6. Most track races use a standing start so the initial velocity would be zero, wouldn't it?

7. I was thinking that for alittle while but not sure. Better safe then sorry :) Thanks for taking the time to help :D
