A person driving her car 45 kph approaches an intersection just as the traffic lights turns yellow. She knows that the yellow light lasts only 2.0 sec before turning red and she is 28 m from the near side of the intersection. Should she try to stop, or she speeds 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 kph to 65 kph in 6.0 sec. Ignore the length of her car and her reaction time.
A. She should speed up to cross the intersection before the light turns red.
B. She should adjust the rate of deceleration and wait for the next red light.
C. She should adjust the rate of deceleration, stop and wait for the next green light.
D. She should maintain the rate of deceleration and continue as she would pass through the intersection against the green light.
C. She should adjust the rate of deceleration, stop and wait for the next green light.

C. 71.24
D. 73.68
