Question

At the instant the traffic light turns green, a car that has been waiting at an intersection starts ahead with a constant acceleration of 3.00m/s2 . At the same instant a truck, traveling with a constant speed of 16.0m/s , overtakes and passes the car.

How far beyond its starting point does the car overtake the truck?
How fast is the car traveling when it overtakes the truck?

Answer 3

I got the first question with ease, but how do you figure out how fast the car is traveling when it overtakes the truck. im confused on that part

Answer 4

You can use:\[\large V_f^2=V_i^2+2ad\]and solve for Vf.

Or, since you've probably already calculated the time, you can use:\[\large V_f=V_i+at\]
