Question
Find the kinetic energy in MeV of a neutron with a measured life span of 2065 s, given its rest energy is 939.6 MeV, and rest life span is 900 s.
Step 1
It is given by the equation: \[KE_{\mathrm{rel}} = (\gamma - 1) \cdot mc^2\] where \(\gamma\) is the Lorentz factor, \(m\) is the rest mass of the particle, and \(c\) is the speed of light. Show more…

Find the velocity and kinetic energy of a 6.0 -fm neutron. (Rest mass energy of neutron is $E_{0}=940 \mathrm{MeV}$.)
What is the kinetic energy in MeV of a $\pi$ -meson that lives $1.40 \times 10^{-16} \mathrm{s}$ as measured in the laboratory, and $0.840 \times 10^{-16} \mathrm{s}$ when at rest relative to an observer, given that its rest energy is 135 $\mathrm{MeV}$ ?
A lambda hyperon $\Lambda^{0}$ (mass $=1115 \mathrm{MeV} / c^{2}$ ) at rest decays into a neutron $\mathrm{n}$ (mass $=940 \mathrm{MeV} / \mathrm{c}^{2}$ ) and a pion (mass $=135 \mathrm{MeV} / c^{2}$): $$\Lambda^{0} \rightarrow \mathrm{n}+\pi^{0}$$ What is the total kinetic energy of the neutron and pion?
