## 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=?
