Question: A lambda hyperon 0 (mass = 1115 MeV/c2) at rest decays into a neutron n (mass = 940 MeV/c2) and a pion (mass = 135

A lambda hyperon Λ0 (mass = 1115 MeV/c2) at rest decays into a neutron n (mass = 940 MeV/c2) and a pion (mass = 135 MeV/c2):
Λ 0 → n + π0
What is the total kinetic energy of the neutron and pion?
