Question

A spaceship has reaced the speed of 0.1c. In an experiment onthe ship, an electron beam takes 1Sec(1x10-6Sec)to cover a distance between two sensors 30 meters apart. That sameexperiment is recored from a stationary planet as the ship passesover head. What is the time travel of the electron beam as seen on theplanet? A spaceship has reaced the speed of 0.1c.

Explanation / Answer

speed of spaceship v = 0.1c time taken by electron beam t = 1s = 1 * 10^-6 s distance between sensors d = 30 m the time travel of the electron beam as seen on the planetis t = (to/(1 - v^2/c^2)^(1/2)) or to= t * (1 - v^2/c^2)^(1/2)
