1st TIME ON INTERNET: COOL METHOD TO FIND THE VELOCITY OF BULLET

2011-02-24T21:51:00.000-08:00

On internet you can find many websites (http://www.youtube.com/watch?v=Lkuo6nZ6nZM) describing the method of pendulum to find the velocity of bullet. Here they use the concept of momentum conservation. But this method is not the perfect one as you need accurate measurement of length and heights to measure the velocity. In some websites you may find the use of moving drum camera .........

In this article i have described a method using circular motion to find the velocity of bullet which is simple and error free.

Look at the fig to understand the apparatus required to find the velocity::

The speed of the bullet can be determined by allowing the bullet to pass through two rotating paper discs mounted at a distance "d" apart on the axle. the angular velocity of axle is know and the value is "ω".

Then fire the bullet. The bullet first makes a hole in the first disc at "A" ( see fig.). Then moving a distance "d" it again makes a hole at point "B" in the second disc. Time taken by the bullet in moving a distance "d" is given by:

T=d/v -------(i)

where v is the velocity of bullet

Now there is a angular displacement "Ѳ" between the two discs as the second disc has rotated through an angle Ѳ in the same time interval "T" and T is also given by

T=Ѳ/ω --------(ii)

from eq. (i) and (ii) it is clear that

T=Ѳ/ω=d/v

SOLVING:

v=dω/Ѳ

d,Ѳ,ω are known so velocity "v" can be calculated .

NOTE:

ω should not be very large or very small

disc should be made of paper and of large radius

paper disc is used so that the bullet's momentum remains constant

WHAT IS KRIYA YOGA???

Kriya Yoga is an ancient technique for self-realization which is well known in India. Through Paramahansa Yogananda and his "Autobiography of a Yogi" it became popular in the West in the 1920s, yet it remains a mysterious and fascinating spiritual path. It is taught by a limited number of masters, most of whom are Indian. Paramahansa Yogananda arrived in the United States in 1920, where he taught Kriya Yoga in accordance with his master's request. The transmission of this teaching has been continued without interruption ever since. Several masters have in the past come to Western countries to teach Kriya Yoga so that it is available to everyone.

ABOUT BABA:

Swami Shankarananda Giri is a spiritual heir in this tradition, and teaches these techniques in its original form as they were transmitted by the lineage of masters. Those who desire to receive instructions in this path as a means for spiritual evolution, may take contact with one of the centres. Swami Shankarananda Giri has been teaching Kriya Yoga techniques in India since 1974, and in Europe since 1978. He has also inherited the astrological system called Cosmic Astrology from his master Swami Narayana Giri ("Prabhujee"). This system was established by Shri Yukteswar.

Swami Shankarananda Giri is also the founder of three schools in India. The first school ,running for over fifteen years, is named after his Guru and has over 1000 students following the Indian Government defined curriculum as well as support for poort students (financial support), ayurvedic medical treatments, hatha yoga, meditaton, school library and computer lab classes.
