Question

Time dilation 1 2 34 You are on Earth and observe three starships: Starship A, with a clock placed aboard and traveling at speed v c/3 relative to Earth Starship B, traveling at speed v c/3 relative to Earth in the same direction as Starship A. Starship , traveling at speed v = c/3 relative to Earth, but in the opposite direction. 1) In which frame of reference can we measure a time interval equal to the time interval measured by the clock aboard Starship A?

Explanation / Answer

1.

It should be spaceship B.

2.

As the relative velocity of B wrt A is zero, spaceship B is at rest in A's reference frame and spaceship A is at rest in B's reference frame. So, in B's reference frame, we can measure a time interval equal to the time interval measured by the clock aboard spaceship A.

3.

It should in C's reference frame.

4.

As the relative velocity of C wrt either A or B is greater than the relative velocity of A wrt B(which is zero), C would be moving fastest wrt A(or B) and hence more time dilation and longer time interval.
