(II) What is the uncertainty in the mass of a muon
(m = 105.7 MeV/c²), specified in eV/c², given its lifetime
of 2.20 μs?

(II) A radioactive element undergoes an alpha decay with a
lifetime of 12 us. If alpha particles are emitted with 5.5-MeV
kinetic energy, find the percent uncertainty AE/E in the
particle energy.
(6) Suppose an atom of iron at rest emits an X-ray photon of energy 64 keV. Calculate the recoil
momentum and kinetic energy for the atom. (You should look up mass for iron, and think
about whether you need to use the relativistic kinetic energy for the atom or if the classical
expression is good enough.)
