- Chapter 37, Problem 025 = 780 m. As detected by observer S', the two flashes Observer S detects two flashes of light. A big flash occurs at x1 = 1390 m and, 5.13 µs later, a small flash occurs at x2 occur at a single coordinate x'. (a) What is the speed parameter of S', and (b) is S' moving in the positive or negative direction of the x axis? To S', (c) which flash occurs first and (d) what is the time interval between the flashes? (a) Number Units (ь) (c) (d) Number UnitsRecall, from this chapter, that the factor gamma (γ) governs both time dilation and length contraction, where When you multiply the time in a moving frame by γ, you get the longer (dilated) time in your fixed fame. When you divide the length in a moving frame by γ, you get the shorter (contracted) length in your fixed frame. Assume that rocket taxis of the future move about the solar system at half the speed of light. For a 1-hour trip as measured by a clock in the taxi, a driver is paid 10 stellars. The taxi-driver’s union demands that pay be based on Earth time instead of taxi time. If their demand is met, show that the new payment for the same trip would be 11.5 stellars.A rocket moves with a velocity of 0.832c to the right with respect to a stationary observer A. An observer B moving relative to observer A finds that the rocket is moving with a velocity of 0.940c to the left. What is the velocity of observer B relative to observer A? (Hint: Consider observer B's velocity in the frame of reference of the rocket. Give your answer to three significant figures. Let the positive direction be to the right. Indicate the direction with the sign of your answer.)
- A clock is placed in a satellite orbits the Earth with a period of 117 minutes. a) By what time interval will this clock differ from an identical clock on Earth after 2 years? b) If the two clocks differ by 2 s, how much time will have passed on Earth? (Assume special relativity applies, and neglect general relativity.)Suppose 5 rocketships are all traveling in â in some frame S. The speeds are: St (min) 100 B 0 0.25 0.5 0.75 0.99 7 1 How much time passes on the clocks inside each rocketship if 100 minutes elapse on the stationary rocketship?The distance between two light pulses moving along the x-axis of the frame S is 2km. What is the distance between them from the point of view of an observer moving at a speed of 0.2c along the x-axis relative to S?
- An astronaut floating in the International Space Station moves at 0.40 m/s to the right. After 5.0sec have passed they are now moving at 1.30 m/s to the left. What was their acceleration duringthis time, stating both the magnitude and direction?A person on Earth observes two rocket ships moving directly toward each other and colliding as shown in the figure below. At time t = 0 in the Earth frame, the Earth observer determines that rocket A, travelling to the right at vA = 0.80c, is at point a, and rocket B is at point b, travelling to the left at vB = 0.60c. According to the Earth observer they are separated by a distance l = 4.2 x 108 m as shown in the other figure. How much time will elapse in frame A from the time rocket A passes point auntil collision?The inertial reference frames, S and S', both share the same origin at t =t'=0. The S' frame is moving at a speed 0.700c in the positive direction, as seen by frame S. An event happens at (t',x', y', z') (300s, 2.50x10"m, 1.50x10"m, 2.90x10"m), as observed in the S' frame. What are the spacetime coordinates in the S frame?
- Two radar pulses sent from the earth at 6:00 am and 8:00 am one day bounce off an alien spaceship and are detected on earth at 3:00 pm and 4:00 pm (but you aren’t sure which reflected pulse corresponds to which emitted pulse). Is the spaceship moving toward earth or away? If its speed is constant (but less than c), when will it (or did it) pass by the earth? (please draw a spacetime diagram.)Clock A travels to the right at a speed v = √(11/13)c relative to clocks B and C. As A passes B, all clocks read 12:00 (shown in the figure below). These readings could be seen simultaneously by a stationary observer O, midway between B and C, though O would make the observation at some later time (a) Clock C reads 6:00 as A passes C.
