URGENT HELPPPPPPPPPPPP PLEASE.. physics... thanks.. thnx?
An alpha particle (mc^2 = 3.7284Gev) with kinetic energy 24.0 MeV strikes a N-14 nucleus (mc^2 = 13.0438 GeV) at rest. An O-17 nucleus (mc^2 = 15.8154GeV) and a proton (mc^2 = 938.8GeV) are produced. The proton is emitted at 90degrees with respect to the direction of the incident alpha particle.
A. Determine the kinetic energies of the 0-17 nucleus
B. Determine the direction that 0-17 nucleus move with respect to the initial alpha particle direction.
PLEASE PHYSIC GENUISES..THANKS A LOT.. HELP ME PLZ
