# Question: a Using the relativistic expression for total energy E and

(a) Using the relativistic expression for total energy E and the magnitude p of the momentum of a particle, show that the two quantities are related by E2 = p2c2 + (mc2)2.

(b) Use this expression to deter-mine the linear momentum of a proton with a kinetic energy of 1000 MeV.
