Question

A star is 33.6 light-years from Earth. Part A How long would it take a spacecraft traveling 0.950c to reach that star as measured by observer on Earth? tEarth = 35.4 years

Correct Significant Figures Feedback: Your answer 35.3684 years was either rounded differently or used a different number of significant figures than required for this part.

Part B How long would it take a spacecraft traveling 0.950c to reach that star as measured by observer on the spacecraft? t = 11.0 years Correct Significant Figures Feedback: Your answer 11.04 years was either rounded differently or used a different number of significant figures than required for this part.

Part C What is the distance traveled according to observers on the spacecraft? l = 10.5 light-years Correct Significant Figures Feedback: Your answer 10.49 lightyears was either rounded differently or used a different number of significant figures than required for this part.

Part D What will the spacecraft occupants compute their speed to be from the results of part B and part C? v = c SubmitMy AnswersGive Up

i only need help with part D

Explanation / Answer

AS asked, I am solving part D only

part B and C conclude that they feel that they have travelled 10.5 light years in 11 years

==> they speed = (10.49/11.04) c = 0.9502c ~ 0.95c
