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 197nucleons.
a) What is the speed of each Au nucleus just beforecollision?
b) What is the momentum at that instant?
c) What energy and momentum would be measured for one ofthe Au nuclei by an observer in the rest system of the other Aunucleus?
