A free neutron has a mean lifetime of about 14.9 minutes when it is viewed from an inertial reference frame at rest with respect to the neutron. The neutron has a mass of 1.675 x 10^-27 kg. a. If the neutron is traveling at 0.9995 c, what is its lifetime as measured by a lab-based (Earth-based) observer?

b. What is the neutron's rest energy in MeV (mega electron-volts)? Conversion: 1 MeV=1.602 x10^-13

c. What is the neutron's kinetic energy in MeV when it is traveling at 0.9995c?
