Example 2: A meter stick moves at 0.9c<br />
relative to an observer. What is the relative<br />
length as seen by the observer?<br />
L<br />
L v c<br />

2 2<br />
L(1 m) 1 (0.9 c) / c<br />
2 2<br />
L (1 m) 10.81 0.436 m<br />
L o<br />
L = ?<br />
1 m<br />
0.9c<br />
Length recorded by observer:<br />
L = 43.6 cm<br />
If the ground observer held a meter stick, the<br />
same contraction would be seen from the ship.
