The light isotope of lithium, 5Li is unstable and breaks up spontaneously into a proton (hydrogen nucleus) and an particle (helium nuclus). In this process, a total energy of 2.75 10-13 J is released, appearing as the kinetic energy of the two reaction products. Determine the speeds of the proton and the particle that arise from the decay of a 5Li nucleus at rest. (Note: The masses of the proton and particle are mp = 1.67 10-27 kg and m = 4mp = 6.68 10-27 kg.)
