I'm confident in debates when I have facts, and good examples.
Answer:
R. P. may be suffering a stroke or psychological problems. Your family should discuss the possibility of taking you to specialist doctors who can quickly diagnose his case and provide correct treatment.
Explanation:
As seen in the question above, R.P. is showing signs of drunkenness, even though he has not drunk any alcoholic beverage for years. This can indicate psychological problems, showing the need of the R.P. family to take him to a psychiatrist who can help him.
However, R.P. may be showing signs of stroke. These signs can be mistaken for drunkenness, because stroke causes the death of some brain cells, as it does not allow the region where these cells are to be irrigated with blood. In that case, the R.P. family should immediately call an emergency service that will help him as soon as possible.
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.
