6) (5 marks) Imagine a stationary rod of length l in reference frame ( with ends at 2A = 0 and xb = l. Show that the length contraction l'=lV1 – u2/c2 can be derived by calculating the time At an observer in O' measures for the rod to pass her origin and then multiplying by its speed, u.
Imagine a stationary rod of length l in reference frame ( with ends at 2A = 0 and xb = l. Show that the length contraction l' = (v1 – u2/c2 can be derived by calculating the time At' an observer in O' measures for the rod to pass her origin and then multiplying by its speed, u.
6) (5 marks) Imagine a stationary rod of length l in reference frame o with ends at 2A = 0 and 2B = l. Show that the length contraction l'=1/1 - u2/e? can be derived by calculating the time At' an observer in O' measures for the rod to pass her origin and then multiplying by its speed, u.
3. (6 marks) A rod of length L'-4m is moving in frame y s S' with respect to a stationary observer in frame S. The rod makes an angle e' 60 to the direction of travel in the S' frame. What is the length and orientation of the rod as measured by a stationary observer in the S frame if the relative speed of the frames is อ' 0.5c as shown in the diagram.
