You are packing for a trip to another star, and on your journey you will be traveling at a speed of 0.99c. Can you sleep in a smaller cabin than usual, because you will be shorter when you lie down? Explain your answer
1.No; from your perspective you’re at rest with respect to the cabin, so you will measure yourself as having your normal length, and will require a normal-sized cabin.
2.Yes, if your bed is oriented along the direction of motion, because length contraction only takes place along this direction.

A. The force on A is half the force on B. B. The force on B is half the force on A. C. The force on A is four times the force on B. D. The force on B is four times the force on A. E. There is no net resultant force on either as long as they stay on the road while turning.
