Textbook Problem

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 900s.

To determine

The kinetic energy.

Explanation

Given data:

Time dilation πMesonis Δt=2065s

Time Δt0=900s.

Rest energy is E=939.6MeV

Formula used:

The equation for time dilation is,

  Δt=γΔt0γ=ΔtΔt0    ...... (1)

The relativistic kinetic energy is,

  K.Erel=(γ1)mc2
