A particle decays: . Calculate the total kinetic energy of the decay products.
The total kinetic energy of the decay energy is.
The law of conservation of energy is define as the energy can neither be created nor destroyed, only converted from one form of energy to another form.
The given reaction is written as:
Solve the total kinetic energy of the decay energy as follows:
Substitute the values from the standard data
Thus, the total kinetic energy of the decay energy is.
The rest energy of many short-lived particles cannot be measured directly but must be inferred from the measured momenta and known rest energies of the decay products. Consider the meson, which decays by the reaction. Calculate the rest energy of the meson given that the oppositely directed momenta of the created pions each have a magnitude 358.3 MeV. See Table 44-4 for the rest energies of the pions.
