You are driving your car and the traffic light ahead turns red. you apply the breaks for 3.0 s, and the velocity of the care decrease for +4.5 m/s. if the cars deceleration has a magnitude of 2.7 m/s^2, what is the cars displacement during this time?

Your statement " the velocity of the care decrease for +4.5 m/s. " does not make sense. You have already said the time interval of deceleration is 3.0 s. Please type the question more carefully.
