I'm having issues with some spaceship relativity problems. Can you please explain them? A spaceship flies by Earth at a high speed. 1. An observer on earth notices a flash of light at the front of the spaceship slightly after a flash of light at the back of the spaceship. What does an observer on the spaceship observes? (A: need more info to determine) 2. An observer on earth notices a flash of light at the front of the spaceship...
Observer O sees a red flash of light at the origin at t = 0 and...
Observer O sees a red flash of light at the origin at t = 0 and a blue flash of light at x = 3.19 km at a time t = 7.56 μs. What are the distance and the time interval between the flashes according to observer O', who moves relative to O in the direction of increasing x with a speed of 0.630c? Assume that the origins of the two coordinate systems line up at t = t' =...

(1) Observer S (at x 0) sees a flash of red light at XR 1200 m from her position and a flash of blue light at x,-480 m on the same straight line. She measures the time interval between the flashes to be 5 us, with the blue flash occurring first (that is, ted ue 5 Hs.) What is the velocity v of observer S' who records the flashes as occurring at the same place, that is, who measures Ax...

2. An observer S sees a flash of red light 1200 m from his position and a flash of blue light straight line. He measures the time interval between 720 m closer to him and on the same the occurrences of the flashes to be 5 microseconds, the red flash occurring first. a. What is the relative velocity v of a second observer S' who would record these flashes as occurring at the same place? b. From the point of...

Imagine a spaceship traveling at a constant speed through outer space. The length of the ship, as measured by a traveler aboard the ship, is 30.8 m. An observer on Earth, however, sees the ship as contracted by 19.7 cm along the direction of motion. What is the speed of the spaceship with respect to the Earth? (Express the speed as a fraction of c, the speed of light in a vacuum.) v c =

05. Light from a spaceship is observed, then the spaceship moves directly away from the observer at high speed while still emitting the light. As a result, the light seen by the observer has: A. a higher frequency and a longer wavelength than before B. a lower frequency and a shorter wavelength than before C. a higher frequency and a shorter wavelength than before D. a lower frequency and a longer wavelength than before E. the same frequency and wavelength...

1. The control panel on a spaceship contains a light that blinks every 3.01 s as observed by an astronaut in the ship. If the spaceship is moving past Earth with a speed of 0.743c, determine the proper time interval between blinks and the time interval between blinks as observed by a person on Earth. A. the proper time interval (in s) between blinks ___________ s B. the time interval (in s) between blinks as observed by a person on...

13. A bicycle rider traveling east at 10 km/hr sees a blue car pass her appearing to travel west at 50 km/hr. What is the blue car’s apparent speed for an observer riding in a red car traveling 15 km/hr west relative to the Earth? A. 40 km/hr B. 15 km/hr C. 25 km/hr D. 35 km/hr E. 65 km/hr 14. Kira flies her spaceship at 0.8 c, trying to catch up to her sister Aja, who’s spaceship is traveling...
