How fast must an object move before its length appears to be contracted to one-half its proper length?
notsponge [240]

The object must move with the speed of \frac{\sqrt{3} }2} 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:

\frac{L}{L'} = \sqrt{(1) - (\frac{v}{c})^{2}

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

\frac{L}{L'}= \frac{1}{2} and \frac{v}{c} = r then,

\frac{1}{2} = \sqrt{1 - r^{2} }\\\frac{1}{4} = 1 - r^{2}\\r^{2} = \frac{3}{4}

Hence, r = \frac{\sqrt{3} }{2}

Therefore, the answer is the object must travel at a speed of \frac{\sqrt{3} }{2} times the lightspeed to be contracted to one-half its proper length.
