Q1. A person driving her car at 43 km/h approaches an intersection just as the traffic light turns yellow. She knows that yellow light lasts only 2.0 s before turning to red, and she is 30 m away from the near side of the intersection. The intersection is 15 m wide. Her car's maximum deceleration is -6.8m/s2, whereas it can accelerate from 43km/h to 70km/h in 8.1 s. Overlook length of her car and her reaction time.

Q2. A scuba diver is 38m below the surface of a lake, where the temperature is 5 °C. He releases an air bubble with a volume of 17cm3. The bubble rises to the surface, where the temperature is 25°C. Presume that the air in the bubble is always in thermal equilibrium with the surrounding water, and assume that there is no exchange of molecules between bubble and the surrounding water. What is the volume of bubble right before it breaks the surface? Hint: consider that the pressure also changes.
