What is the final kinetic energy of the gold nucleus

Reference no: EM13342032

An alpha particle (a helium nucleus, containing 2 protons and 2 neutrons) starts out with kinetic energy of 9.9 MeV (9.9x106 eV), and heads in the +x direction straight toward a gold nucleus (containing 79 protons and 118 neutrons). The particles are initially far apart, and the gold nucleus is initially at rest. Answer the following questions about the collision.

What is the initial momentum of the alpha particle? (You may assume its speed is small compared to the speed of light).

What is the initial momentum of the gold nucleus?

What is the final momentum of the alpha particle, long after it interacts with the gold nucleus?
