At the instant a traffic light turns green, a car that has been waiting at the intersection starts ahead with a constant acceleration of 2.00 m/s2. At that moment a truck traveling with a constant velocity of 15.0 m/s overtakes and passes the car.
(a.) Calculate the time necessary for the car to reach the truck.
(b.) Calculate the distance beyond the traffic light that the car will pass the truck.
(c.) Determine the speed of the car when it passes the truck.
