a) they both travel the same distance in the same time.
distancecar=distancetruck
1/2 * 2.85*t^2=19*t
solve for t, then solve for either distance.
b) vf=2.85*t
At the instant the traffic light turns green, a car that has been waiting at an intersection starts ahead with a constant acceleration of 2.85m/s^2. At the same instant a truck, traveling with a constant speed of 19.0m/s, overtakes and passes the car.
A) How far beyond its starting point does the car overtake the truck?
B) How fast is the car traveling when it overtakes the truck?
