Kinetic Energy in an Inelastic Collision
A neutron with an initial kinetic energy of 5.0 MeV collides with a carbon-12 nucleus that is initially at rest. During the collision, 20% of the neutron’s initial kinetic energy is converted to internal energy of the nucleus. What is the final kinetic energy of the neutron?
A
3.43 MeV
B
2.5 MeV
C
4.0 MeV
D
1.0 MeV
