The object must move with the speed of 
times to approximately seeing that it is contracted to exactly half of its actual length.
<h3>How is this calculated?</h3>
The length contraction experimented by the object as it approaches lightspeed, in meters per second, is described by Lorentz contraction formula:
Here, v is the current speed m/s
c is the speed of light in m/s
L' is the length of the object at rest in m
L is the length of the object at the current speed in m
Now we know that
and 
then,
Hence, r = 
Therefore, the answer is the object must travel at a speed of times the lightspeed to be contracted to one-half its proper length.

Answer:
La igualdad significa que todos los seres humanos tienen el mismo valor y deben ser tratados por igual. Así que necesitamos tratar a todos con respeto sin importar su raza, género, o si su parte de la comunidad LGBTQ, o con quién sales y quién eres. Así que es un derecho que necesitamos, y que tenemos que seguir. Al igual que "Las vidas negras importan". ( Black Lives Matter)

Translation in English
Equality means that all human beings have the same value and must be treated equally. So we need to treat everyone with respect regardless of race, gender, or whether they are part of the LGBTQ community or who your with and who you are. So it's a right we need, and a right that we need to follow. Just like "Black Lives Matter."
Hope this helped!
