PLEASE DO ALL QUESTIONS WITH WORK! T = KINETIC ENERGY
2. In the lab a meganeutron (1 kg) approaches a megaalpha (4 kg) that's standing still and they elastically scatter (T conserved). The meganeutron is initially moving at 1000 m/s in the +x direction. Nonrelativistic. Use kg, m/s, kg m/s, J lab frame question:s a) what are the initial velocities in the lab frame? b) what are the initial total kinetic energy and momentum in the lab frame? converting to...
