Consider an anti-proton (rest mass = 1.007 825 amu) whose kinetic energy is 450 MeV.

• Compute the ratio v/c (particle speed divided by speed of light) using both the classical expression and the relativistic expression for kinetic energy? How much error (in %) is incurred by using the classical expression?  
• Compute the magnitude of the anti-proton’s momentum using both the relativistic and classical formulas. Provide you answers in units of MeV/c.
