I understand what you're saying but what I'm trying to say to him is that in a real life situation things won't happen like that at the track.

I am saying that a vehicle with about the same weight but one having more power should be faster in the 1/4 mile but there are other things that can play effect to it in real life, I'm just trying to specify the difference between the 2.

 

Bingo...perfect example.

 

in another example, Goliath should have slaughter David.

 

but really, my cobolt should be a lot fast then it should be-if the driver(me) lost about 75 pounds!

 

Theoretical is never the same as actual. Theoreticly a 2.4 is around a half second faster then a 2.2 with all varibles constant. But constant varibles hardly happen in a 1/4 mile race so actually anything could happen. So there is a % of error due to unconstant and uncrontolable varibles. That means that while the .5 differnece is a good rule of thumb it could be anywhere from 1.5 second difference to even the 2.2 having a better time then the 2.4.

 

Exactly.

 

so is 1/2 sec really matter? does it make that much of a difference?

 

Yes. .5 of a second makes a good difference of length in a race.

 

deffinatly does i agree
