A spaceship, 200 m long as seen on board, moves by the Earth at $0.970 c .$ What is its length as measured by an earthbound observer?
Added by Donald M.
Step 1
970c, where c is the speed of light. This is a significant fraction of the speed of light, so we need to take into account the effects of special relativity. Show more…

A spaceship, 200 $\mathrm{m}$ long as seen on board, moves by the Earth at 0.970 $\mathrm{c} .$ What is its length as measured by an Earth-bound observer?
A spaceship is moving at a constant velocity of $0.70 c$ relative to an Earth observer. The Earth observer measures the length of the spaceship to be $40.0 \mathrm{m}$. How long is the spaceship as measured by its pilot?
The crew of a rocket that is moving away from the earth launches an escape pod, which they measure to be 45 $\mathrm{m}$ long. The pod is launched toward the earth with a speed of 0.55$c$ relative to the rocket. After the launch, the rocket's speed relative to the earth is 0.75$c .$ What is the length of the escape pod as determined by an observer on earth?
