I find this really hard to understand

**hy**, Sunday, November 7, 2010 at 12:30amwill it hit?

use final velocity of 0 presuming that it came to a halt

find the time elasped for it to stop using acceleration = change in v over change in t

use the time to find how far both have traveled...

yes it will hit

it;s an equation of what time used for second car to travel 300+11t

since we don't know the final velocity cant use equations of it

so use change in x = intial v (t) + 1/2 a t^2

so 300+11t=22t+(-2)t^2

2t^2-11t+300=0

using solve t using quadratic formula to see what time will it hit
