A spacecraft of the Trade Federation flies past the planet Coruscant at a speed of 0.610 c. A scientist on Coruscant measures the length of the moving spacecraft to be 71.0 m. The spacecraft later lands on Coruscant, and the same scientist measures the length of the now stationary spacecraft. What value does she get?

the length of the now stationary spacecraft = 89.65m

Explanation:

In contraction equation, Length contraction L is the shortening of the measured length of an object moving relative to the observer's frame.

Thus, it has a formula;

L = L_o (√ (1 - (v²/c²))

Where in this question;

L = 71m and v = 0.610 c

Thus;

71 = L_o (√ (1 - ((0.61c) ²/c²))

c² will cancel out to give;

71 = L_o (√ (1 - 0.61²)

71 = L_o (√ (1 - 0.61²)

71 = 0.792L_o

L_o = 71/0.792

L_o = 89.65m
