You can only consult SE, RM, and class notes. Web resources, additional texts, or consultations with other people are not allowed. B. You can bring the final project to my office, Dunning N203, or leave it in my mailbox at the secretary's office in Dunning's first floor. Late papers will not be accepted. C. Your answers ought to be legible and clear! Due Date: On or before 11:30 am, Monday, May 9, 2016 At a security checkpoint two barriers are simultaneously lowered and immediately raised. A passenger notes that her spaceship, at rest at the checkpoint, is slightly smaller than the distance between the two barriers. Now assume that the spaceship is moving toward the checkpoint at 80% the speed of light. According to the guard at the checkpoint there will be a moment when the spaceship passing through the gates will fit comfortably inside the two barriers when they are lowered and raised because of length contraction. But the passenger reasons that in her moving frame the distance between the two barriers will be contracted, therefore her spaceship will not fit inside the two barriers. Who is right? Is the interpretation of the passenger correct? Is there any possibility to reconcile the two viewpoints? Please explain in detail what does happen in each frame. Write your answer in the allowed space. References: SE and class notes only.

Explanation / Answer

length contraction is only experienced by the person who is in the frame which travels with near speed of light.

but this is not true in actual case.

so the guard does not feel the length contraction but the passenger feels it.

the inter pretation of passenger is not correct . Because actually it does not happen.
