1/2 a t^2 = v t ... 1/2 * 3.55 * t^2 = 22.0 t ... 1/2 * 3.55 t = 22.0
a. d = v t = 22.0 t
b. v = a t = 3.55 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 3.55 m/s2 . At the same instant a truck, traveling with a constant speed of 22.0 m/s , overtakes and passes the car.
