Thank you for the feedback! However, your formula for the relativistic kinetik energy is missing a root where the lorenz factor is defined. Upon calculations, I found that: 1) according to relativity v of alpha particle = 0.021971251c 2) according to classical physics v of alpha particle =...

Thank you for this feedback! However, I am still confused as to how to show what fraction of the speed of light this kinetic energy for each helium atom is. If I use the relativitity formula, do I use the mass of each helium atom separately, and what units do I use?

Ok, I see what you are saying: The kinetic energy of the alpha particle=Binding Energy of beryllium - Binding Energy of the two Helium atoms

Homework Statement The nucleus of beryllium with mass number 8 decays into two alpha particles. The nuclear masses are M(8Be)=7456.6 MeV/c^2 and m(4He)=3727.4 MeV/c2. Assume that 8Be decays at rest and that we can neglect the atomic electrons. We are asked to find a) the kinetic energy of...
