A person driving her car at 35km / h approaches an intersection just as the traffic light turns yellow. She knows that the yellow light lasts only 2.0 s before turning to red, and she is 28 m away from the near side of the intersection (Fig. 2-49). Should she try to stop, or should she speed up to cross the intersection before the light turns red? The intersection is 15 m wide. Her car's maximum deceleration is -5.8 m/s2, whereas it can accelerate from 45 km / h to 65km / h in 6.0 s. Ignore the length of her car and her reaction time.
