Gold (Au) nuclei are accelerated to a totalenergy of2 GeV per nucleon, as measured in lab reference frame.Each Au nucleus contains 197 nucleons (nucleon refers to proton or neutron). The mass for a nucleon is assumed to be 1 amu (atomic mass unit), which has a rest mass of 931.5 ????2⁄.(a) What is the speed of each Au nucleus? (b) What is the momentum of each Au nucleus?
