- 1) Two identical atomic clocks are manufactured at a factory. One clock remains at the factory, and the other is transported across the country to a physics lab. When the clock arrives at the physics lab, it reads 9:00 a.m. At this same time, does the clock at the factory read a time that is before 9:00 a.m., equal to 9:00 a.m., or after 9:00 a.m.? Explain. 2) Suppose you are a traveling salesman for SSC, the Spacely Sprockets Company. You travel on a spaceship that reaches speeds near the speed of light, and you are paid by the hour. (a) When you return to Earth after a sales trip, would you prefer to be paid according to the clock at Spacely Sprockets universal headquarters on Earth, according to the clock on the spaceship in which you travel, or would your pay be the same in either case?

- A passenger train leaves a railway station at 12:00 pm and travels 3 hours on the Northbound tracks. A second passenger train leaves the same railway station at 12:45 pm and travels 2 hours and 15 minutes onthe Southbound tracks at a speed of 20 kilometers per hour faster than the first train. At 3:00 pm the two trains were 360 kilometers apart. How fast was each train traveling? How do I setup this equation?Because of the earth’s rotation, a person living on top of a mountain moves at a faster speed than someone at sea level.
