9. 10. 11. Bob ies at relativistic speed from Los Angeles to New York City. While on the ight, Bob determines the distance he travelled using d=vt. You, on the ground, determine the distance travelled using meter sticks. a. Who, if anyone, measures the proper length? Explain. b. Who, if anyone, measures the slightly shorter distance? You are in car A and Bob is in car B. As you both drive on the freeway, car A is traveling faster than car B. So, car A comes up from behind car B and passes it. You want to know how much time is requires for car A to completely pass car B, from no overlap between the cars to no overlap between the cars. a. Specify the two events in this situation. Be specific and refer to the front and back bumpers of both car A and B. b. Who, if anyone, measures the proper time between the events? Explain. There are two bars, A and B, where Bar A is moving at a V relativistic speed, v. When Bar B observes the two bars, they measure as the same length so LA=LE. When Bar A observes the two bars, are they the same length? If they are the same length, explain why. If they are not the same length, which is longer? Explain
