Extra: A very rare but occasionally observed decay of a muon u (rest energy = 106 MeV) is nto an electron e (rest energy 0.511 MeV) and a photon y (rest energy decays at rest by this mode, what is the kinetic energy of the electron and photon combined after the decay? (1MEV = 10°eV = 1.6 x 10-13 J) zero). If a muon

The lifetime of a muon is 2.20 ?s. If you measured its mass to be 105.7 MeV/c2, what would be the minimum (Heisenberg) uncertainty in this value? Sketch the situation, defining all of your variables

What is the rest energy that corresponds to a small amount of table salt (mass = 0.54 grams)? Recall that 1 g = 10-3³ kg. E = J Note: you can enter your answer using exponential notation using "E": for example, 1.23 x 1012 i- expressed as 1.23E12.

An alpha particle is the nucleus of a He-4 atom and has a rest mass of 3727.38 MeV/c2. How much energy is required to accelerate an alpha particle from rest to 0.6c? What is the momentum of the alpha particle once it reaches this speed? Would more, less or the same amount of energy be required to accelerate a proton from rest to this speed?
