Homework Statement
at the instant the traffic light turns green, an auto mobile starts with a constant acceleration of 2.2 m/s^2. At the same instant, a truck traveling with a constant speed of 9.5 m/s overtakes and passes the car.
a) how far beyond the traffic signal will the auto mobile overtake the truck?
b) how fast will the car be traveling at that instant?
Homework Equations
if I am only given the acceleration of the car and the velocity of the truck (the implied initial velocity is 0) how am i supposed to answer any of the questions?
The Attempt at a Solution
Given(car): a= 2.2 m/s^2, v1=0, d=?, t= ? given(truck): v= 9.5 m/s, v1= 0, d=?
