The instant a traffic light turns green a car that has been waiting at the light starts forward with a constant acceleration of 10 ft/s^2. At the same instant a truck traveling at a constant 30 ft/s overtakes and passes the car.
1. how far beyond the starting point will the car overtake the truck.
2. how fast willl the car be traveling

The distance both travel is the same
dcar= 1/2 a t^2
dtruck=10 t
set those equal, and solve for t.
then, knowing t, you can find the velocity of the car (a t) and how far it went (1/2 a t^2) 
pls ans. dis tnx
i need help:((
