Question

Prob. 2(8 pts) An airport worker measures the length of a runway to be $L_o$. A spaceship, S flies horizontally in a straight line over the runway with constant speed $v = 0.80c$ with respect to the runway. According to the spaceship's pilot's wristwatch, the time of flight over the runway was $20.0\mu s$. The time measured by the airport's clock for S to fly over the runway was $t_o$. The physical dimensions of S can be neglected. [a] (2 pts) Does the pilot measure the proper time of flight over the runway? [i] yes [ii] no [b] (2 pts) What is the length of the runway as measured by the pilot? [c] (2 pts) What's the value of $L_o$?

[a] (2 pts) Does the pilot measure the proper time of flight over the runway?
[i] yes
[ii] no
[b] (2 pts) What is the length of the runway as measured by the pilot?
[c] (2 pts) What's the value of $L_o$?

Prob. 2(8 pts) An airport worker measures the length of a runway to be Lo. A spaceship, S
flies horizontally in a straight line over the runway with constant speed v = 0.80c with
respect to the runway. According to the spaceship's pilot's wristwatch, the time of flight
over the runway was 20.0μ s. The time measured by the airport's clock for S to fly over the
runway was to. The physical dimensions of S can be neglected.
[a] (2 pts) Does the pilot measure the proper time of flight over the runway?
[i] yes
[ii] no
[b] (2 pts) What is the length of the runway as measured by the pilot?
[c] (2 pts) What's the value of Lo?
