A system consists of a particle of mass m at rest and a photon of energy E = m. What is the total system mass?
Photon is massless
so the total system mass will just be due to the particle
so the total mass is "m"

PHYS10121 a) A particle of rest mass m is travelling so that its total energy is 2mc. It collides with a stationary particle of rest mass m to form a new single particle. What is the 2. rest mass of the new particle? 9 marks] b) A photon hits an electron at rest and produces an electron-positron pair according to the reaction γ+ e- e" + e-+e+, what is the smallest possible photon energy for this to occur? You may...
A particle of mass M decays into a photon and a particle of mass m < M. What is the energy of the particle of mass m in the rest frame of the decaying particle?
3. (4 points) Photon collision! A photon with energy 2m hits a particle of mass m at rest. The photon back-scatters from this intcraction (that is, it movics in the opposite dircction) white the particle moves forward to conscrve momentum. Find the back-scattered photon's encrgy E and the particle's speed |]. (algebraically, not using cnergy momentum diagrams)
Special Relativity A photon of energy E collides with a stationary particle of rest mass m0 and is absorbed. What is the velocity of the resulting composite particle? NOTE: I used consrvation of momentum: p(before) = p(after), therefore p/c (energy of photon) = gamma*m0*v and solved for v. Apparently this is incorrect????
A photon of energy E collides with a stationary particle of mass m0 and is absorbed. (a) Use the reference frame of the stationary particle and draw before and after diagrams, labeling all the particles and their directions of motion (b) Write down conservation conditions relevant to this process. (c) What is the velocity of the resulting composite particle in terms of E and m0?
3. A particle of rest mass m moving in the a direction at a speed of c/3 abruptly decays electromagnetically, yielding two photons. From the perspective of the home frame, the photon moving in the positive r direction is more energetic than the photon moving in the negative r direction - (a) Determine the energies and frequencies of both photons in the rest frame of the decaying particle. -(b) Using Lorentz transformations, determine the energies and frequencies of both photons...
2. An exotic particle with mass 10TeV/c? at rest is hit by a 1TeV gamma particle (a high energy photon). The gamma particle is completely absorbed and the exotic particle is transformed into another one. (a) What is the mass of the resulting particle? (Hint: use E2 = (pc)2 + (mc)). (b) How fast is the resulting particle moving? (c) Is there a frame of reference in which the resulting particle is not moving? if so, what is the energy...

There is a (hypothetical) subatomic particle of mass 2.9e-28 kg at rest. It decays into a daughter subatomic particle of mass 1.1e-28 kg while emiting a photon. (Assume the speed of the daughter is lower than the speed of light.) Find the kinetic energy of the daughter particle. (In Joules) (i got the answer 1.49e-11 but this is not correct)
A particle has a kinetic energy equal three-quarters its rest mass energy. What is the speed of this particle? (Answer in terms of c)
