2. Car A is stopped at a traffic light. Att = 0, the light turns green and A starts up. Just as it does so, car B passes it, going at a steady velocity. Their velocity-time curves are shown in the figure below. 80 70 cor A Velocity (mph) 60 50 car B 40 30 20 10 0.000 0.002 0.004 0.006 0.008 0.010 0.012 0.014 0.016 0.018 Time (brs) (In this problem, you don't have to convert miles to meters, or hours to seconds. Leave the units alone and use the same kinematic formulas. Error checking can be done by including units in your equations to make sure the right quantities are cancelled.) a. How long does it take car A to be going as fast as car B? b. Which car is ahead, and by how much, at the end of 0.010 hour? At what time does car A catch up with car B? C.
