Question

Canadian nuclear reactors use heavy water moderators in which elastic collisions occur between the neutrons and deuterons of mass 2.0 u.

What is its kinetic energy, expressed as a fraction of its original kinetic energy?

I am confused what this question is asking, and how to exactly get there. Any help would be greatly appreciated

Answer 1

I have also found that the weight of the neutron is 1 u

Answer 2

@mathslover could you possibly help?

Answer 3

This solution provides three answers with six steps of calculations. The law of conservation of momentum and Newton's experimental law are used.

Answer 4

thank you
