A person driving her car at 57 km/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 30 m away from the near side of the intersection .Should she try to stop, or should she make a run for it? The intersection is 15 m wide. Her car's maximum deceleration is -6.6 m/s2, whereas it can accelerate from 57 km/h to 70 km/h in 3.9 s. Ignore the length of her car and her reaction time.
If she hits the brakes, how far will she travel before stopping?
19 m (I know how to do this one )
If she hits the gas instead, how far will she travel before the light turns red?
? m (How would I do this one?)
