(III) An automobile traveling 95 km/h overtakes a 1.30-km-long train traveling in the same direction on a track parallelto the road. If the train's speed is 75 km/h, how long doesit take the car to pass it, and how far will the car havetraveled in this time? See Fig. 2–36. What are the resultsif the car and train are traveling in opposite directions?-1.30 km-v = 75 km/hsdesla sia i dedasdasv = 95 km/hvirFIGURE 2–36 Problem 16.

A person driving her car at 35 km/h approaches an inter- section just as the traffic light turns yellow. She knows that the yellow light lasts only 2.0s 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/s?, whereas it can accelerate from 45 km/h to 65 km/h in 6.0 s. Ignore the length of her car and her reaction time. – 28 m - -15 m→ FIGURE 2-49 Problem 73.
