Zosia flies her length L spaceship towards a length 2L space station, which has open doors on each end. How fast must Zosia fly her spaceship so that her ship appears exactly as long as the space station in her reference frame?
A. 0.99 c
B. 0.87 c
C. 0.50 c
D. 0.43 c
E. 0.25 c
If l0 is the proper length in rest frame and l denotes the contracted length in the frame of reference of the observer moving with velocity v then,
c is the velocity of light
For the observer in a spaceship, the contracted length must appear L as compared to the original length 2L
Option B is correct.
Zosia flies her length L spaceship towards a length 2L space station, which has open doors...
Practice Problem 27.3 SOLUTION A spaceship flies past earth with a speed of 0.980c (about 2.97 x 10 m/s) relative to earth. A crew member on the spaceship measures its length, obtaining the value 400 m. What is the length measured by observers on earth? SET UP The length of the spaceship in the frame in which it is at rest (400 m) is a proper length in this frame, corresponding to lo in We want to find the length...
