Question
An astronaut on a spaceship traveling at a speed of $0.50 c$ is holding a meter stick parallel to the direction of motion.a) What is the length of the meter stick as measured by another astronaut on the spaceship?b) If an observer on Earth could observe the meter stick, what would be the length of the meter stick as measured by that observer?
Step 1
In the frame of reference of the spaceship, the meter stick is at rest. Therefore, the length of the meter stick as measured by another astronaut on the spaceship is 1 meter. So, $L = L_0 = 1m$. Show more…

A person in a spaceship holds a meter stick parallel to the motion of the ship as it passes by the Earth with $\gamma=2 .$ What length does an observer at rest on the Earth measure for the meter stick? a) $2 \mathrm{~m}$ c) $0.5 \mathrm{~m}$ e) none of the above b) $1 \mathrm{~m}$ d) $0.0 \mathrm{~m}$
An observer on earth can see a meter stick in a spaceship passing earth. He measures the meter stick length to be 0.850 m. What's the speed (relative to earth) of the spaceship carrying the meter stick? 0.75 C C 0.81 C 0.92 C
A spaceship moves at a constant velocity of $0.40 c$ relative to an Earth observer. The pilot of the spaceship is holding a rod, which he measures to be $1.0 \mathrm{m}$ long. (a) The rod is held perpendicular to the direction of motion of the spaceship. How long is the rod according to the Earth observer? (b) After the pilot rotates the rod and holds it parallel to the direction of motion of the spaceship, how long is it according to the Earth observer?
