Dang I jut whent to brush my theets before answer that and shadow allready did

you made
x = 30m/s * 20s
x = 600m
where should be 30 s
the rest is just like I've made other then more organized

double post, this one is the correct graph with t on the x axis

http://img267.imageshack.us/img267/991/19780307.jpg So the first part of trip is the constant aceleration V goes from 0 to 30 in 20s, so the you got 2 points (0,0) and (20,30) since aceleration is constant you join the two points by a straight. Now second part of trip accelaration=0 so V is constan...

Another way to find the lenght would be by calculating the area under the graph VxT

There is information missing from the question. What about if he started accelerating slowly then all of a sudden went 100% throttle during the last 5 seconds to reach 30m/s? The distance traveled would be drastically different than if he accelerated at a constant rate. I would think the question i...

I was just posting to you check my calcs because i tend to make silly mistakes, specialy on vacations when i realized the lenght of first part is 300 not 100
So total lenght is 1650
that changes average speed too Vav=20,625

Q1. You gotta separate the trip in 3 stages, first he starts from Vo=0 m/s then he get 30m/s in 20 s so his aceleration is of 30/20 m/s^2 so to know the lenght of this stage you use toricelli's formula V^2=Vo^2 + 2*a*(lenght) since Vo=0 in this case you have that the lenght of this stage is 100m, ne...

Pfff My brother just got a 5 years one, mine was 10 but was for tourism.

I laughed when I got my Pre-Calc book. http://i495.photobucket.com/albums/rr316/Durhhhh/stewart_book.png lol I also have J.Stweart calc books vol1 and 2 they are good. I've got this one http://books.gigaimg.com/avaxhome/ed/04/001704ed_medium.jpeg I Believe thats the most used book for calc. Btw cal...

Yz, do you know if I can do some kind of exe file so when I run it, it configures my network adapter from non fixed to a "fixed" fixed IP/DNS? thats simple because somehow the only way I can get most of my download speed is when I change my network to fixed IP, don't ask me why. So with that my pare...

That game sucks bad, plus the video is from F1 2010. Anyway both 2010 and 2011 games sucks.
Last fun game of F1 was F1 challenge from EA, sony's one for ps3 F1 2006 isn't that bad though.

iRacing 8) ...worth the click... That's it? No cars? Does it look THAT much better than previous?(I can't tell) Still trying to find the extra cash. From what I've tested I liked the new tyre model on the skippy. Car handles allot better. Can't say about other cars because just had money for the sk...
