A neon sign in front of a cafe flashes on and off once every 4.0 s, as measured by the head cook.
A. How much time elapses between flashes of the sign as measured by an astronaut in a spaceship moving toward Earth at a speed of 0.86 c?
And my second question is: (it has four parts)
A. Is it possible for you to travel far enough and fast enough so that when you return from a trip, you are younger than your stay-at-home sister, who was born 5.0 yvafter you? (yes or no)
B. Suppose you fly on a rocket with a speed v = 0.99 c for 1 y, according to the ship's clocks and calendars. How much time elapses on Earth during your 1 y trip?
C. If you were 23 y old when you left home and your sister was 18, what is you age when you return?
D. What is your sister's age when you return?
A) Δt' = t / sqrt (1- v^2/c^2)
= t / sqrt (1 - (0.86c)^2/c^2 ----> c^2 cancel
= t / sqrt (1 - .7396)
= 4.0 / sqrt (1 - .7396)
= 7.84 s
B) a) yes
b) same equation as Part A above. (dont convert years to anything, leave as is)
c) 23 yrs + 1 yr of trip = 24 yrs
d) 18 + answser derived in Part b = sister's age after return
