The Relativistic Heavy Ion Collider (RHIC) at Brookhaven iscolliding fully ionized gold (Au) nuclei accelerated to an energyof 200 GeV per nucleon. Each Au nucleus contains 197 nucleons.
a) What is the speed of each Au nucleus just before collision?
b) What is the momentum of each at that instant?
c) What energy and momentum would be measured for one of the Au nuclei by an observer in the rest system of the other Au nucleus?
