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.

When local residents of an area refer to a hurricane, they are
<span>speaking of the violent, stormy weather system that brings torrential </span>
<span>rains and destructive, high velocity winds of over 74 miles per hour. </span>
Hurricanes<span> are also characterised by a heavy cloud cover, which </span>
<span>reduces sunshine and makes visibility and temperatures very low. In </span>
<span>other parts of the world, </span>tropical cyclones<span> are given other names. For </span>
<span>example, in Australia they are known as Willy Willies, in India there </span>
<span>are known as Tropical Cyclones and in the Pacific they are known as </span>
<span>Typhoons. </span>
<span>Hurricanes can only form in tropical regions due to their need for </span>
<span>certain atmospheric and weather conditions only found there. Most </span>
<span>hurricanes originate on the west coast of Africa, in the form of </span>
<span>thunderstorms. As these thunderstorms move westwards over the ocean, </span>
<span>they become low-pressure systems; first in the form of tropical </span>
<span>depressions, then tropical storm and then finally hurricanes. </span>
It was first celebrated in Canada, in 1882. It was brought to the US by the travelers from Canada and it became a national holiday in Canada in 1894.
