hi can anyone here help me solve this???

What was the question?, if unsure which variable do you want me to relate to??

i'm from another forum & a member has posted this problem. i have no idea what it is or what it's asking for.

any info. or input will be helpful

hmm...it appears to be as wolfson says. There doesn't really seem to be a question. What forum are you from, if you give us a link to the original post, perhaps that would shed some light on it?

as I was too hurried to say earlier when I saw this, and these two have just stated, there is no question

 

give a link

 

please

i copied the problem from the posting..

oh btw it's not from a math/science forum... just a motorcycle forum... some one must have dug into his text book or something

E = sqrt( p^2c^2 + m^2c^4)

 

E=f(m, p))

SR:-

E = sqrt( p^2c^2 + m^2c^4)

if

E=mc^2 (m > 0 & p = 0) and

E=pc (m = 0 & p > 0).

 

Let E = f(m, p), where

f(m,p)

=mc^2 (m > 0 & p = 0)

=pc (m = 0 & p > 0)

= '?' ( m > 0 & p > 0)

E=G^2=c^2

 

m = sqrt(c'/c)*m

 

dimension of mc2 is [ M ][ L ]2/[ T ]2

 

These are preliminary answers I have worked, but I will have to study for a bit longer to contribute L^T.

I think the idea is that when E >> p the general formula for the energyof a particle with mass m and momentum p.

 

E = (m^2 + p^2)^(1/2)

 

can be approximated by keeping just the first two terms in the

expansion

 

 

E = p + m^2/2p + ...

 

 

If you kept only the leading term in the expansion you would have

E = p,

which corresponds to a particle that travels at the speed of light.
