1) Let's continue to investigate your space vacation from last week. Your spaceship, which has a proper length of 300 m, passes near a space platform while you are moving at a relative speed of 86% the speed of light (so v=0.86*c). What is the length of the spaceship when measured by someone on the space platform?

Equation for length contraction

L = L' * √ (1 - v2/c2)

Where:

L = The length of the spaceship as seen by the observer

L' = The proper length of the spaceship

v = The velocity of the spaceship

c = The speed of light.
