A person driving her car at 56 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 (Fig. 2-29). 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 -7.0 m/s2, whereas it can accelerate from 56 km/h to 70 km/h in 4.2 s. Ignore the length of her car and her reaction time.(adsbygoogle = window.adsbygoogle || []).push({});

If she hits the gas instead, how far will she travel before the light turns red?

I think there is not enough details given in the question to solve this problem? Is there a way to do this?
