conservation of linear momentum
Neutrons in a nuclear reactor have the Kinetic energy J . The kinetic energy of the neutron is reduced to by a series of collision between the neutron and carbon nuclei in the moderator . On average , the fractional loss of the kinetic energy of the neutron after each collision is 0.14 . how many collisions does a neutron experience in the process ?
My working :
Let the initial Kinetic energy :
Kinetic energy after 1 collision =
After n collisions , the kinetic energy will be
Which one is the correct one and why is it so ?? Thanks for your time .
