Physics Ques.

In nuclear reactors, subatomic particles called neutrons are slowed down by allowing them to collide with the atoms of a moderator material, such as carbon atoms, which are 12 times as massive as neutrons. If the neutron has an initial speed of 1.0×107 m/s, what will be its speed after collision?
