In the SR section of my book there is a question like this.
An astronout is traveling at .9C.
The spacecraft has a proper legth of 100m.
a)what is the length observed by observer? I get this as I divide 100 by gamma which is about 2.29
b)Astronouts view is also effected by the time it takes for the light to reach him. What length spacecraft does he see when the spacecraft s tail is next to him?
I got the answer to be about 39m but in the answers section they have 23m.
Could someone help me with this please.
This is what I have done, is it correct?
43.6/C=1.433333E^-7 Sec. (Time it take the light in front of spacecraft to reach observer)
1.43333E^-7*.9C=39.24m (The length of spacecraft while the tail is next to him.)
