You are driving through downtown Seattle at the posted speed limit of vama. You approach three successive intersections each with a trafc light, as shown in the gure. When you are a distance d to the left of the rst trafc signal, all three trafc signals turn green (allowing you to drive forward). All three trafc lights stay green for a time nights, before changing to red (telling you to stop). van\": 50.0 km/hour 15 m =10. m= 1.0 x 101m Emmr 13 S m=f|- |_ d a. Calculate the time that it will take you to reach the 3rd stoplight. b. Mathematically show whether or not you can drive past the 3rd stoplight without stopping due to the trafc lights. c. A second car is initially stopped at the rst trafc signal when all the lights turn green. At that time it starts to accelerate to the right at a rate of2.00 mfs2. Assuming this driver does not follow the speed limit, mathematically show whether or not this car can drive past the third intersection without stopping due to the trafc lights. By how many seconds will this second car either travel past the 3rd intersection OR not be able to make it? Make a graph of acceleration, include both cars from t = 0 to t = tugm Make a graph of velocity, include both cars from t = 0 to t = tlight Make a graph of position, include both cars from t = 0 to t = tlight terms
