Hey I have a problem concerning relativistic energy
One neutrino has an energy of 10 MeV and a rest mass of 10 eV/c^2. Another neutrino has an energy of 30 MeV and a rest mass of 10 eV/c^2.
Calculate the difference in time that the two particles arrive at Earth if they are emitted from a...
A particle of initial kinetic energy T[SIZE="1"]0 and rest energy E[SIZE="1"]0 strikes a like particle at rest. The initial particle is scattered at an agle theta to its original direction. Show that the final kinetic energy T is
T = T[SIZE="1"]0cos2(theta)/(1+...
a little rough on this simplification, is this correct?
solving for "u"
E = mc^2 / (root)(1-u^2/c^2)
(root)(1-u^2/c^2) = mc^2/E
1 - u^2/c^2 = (mc^2/E)^2
1 = (mc^2/E)^2 + u^2/c^2
c^2 = (mc^2/E)^2 (c^2) + u^2 -> (sq root everything)
u = c - mc^3/E
pretty bad i don't...
all speed are relative to the observer, but if we have 2 planets with inteligent beings and for one of them all the objects in the universe seem to move just a bit slower than the other planet, wouldn't it then be less matter and energy in thge universe for those biengs? and with finite amount...
A pion at rest (m_pi = 273m_e) decays to a muon (mass = 207m_e and an antineutrino (mass = 0). Find the kinetic energy of the muon and the energy of the antineutrino in electron volts.
How am I supposed to start this problem? ANy help would be great...thx!
I am now currently using an introductory modern physics textbook but they did not give me the derivation for relativistic KE for a moving object which is \gamma mc^2 . Is the derivation too difficult to be put in the introductory text?? Anyway, what is its derivation? Thanks alot.
