Calculate the Speed?
A thermal neutron is one that has a kinetic energy of about 1 eV. How fast does a thermal neutron travel?
Kinetic Energy = 1 eV
......................... = 1 * 1.6 * 10^-19 J
Mass of neutron = 1.008665 u
........................... = 1.008665 * 1.661 * 10^-27 Kg

Kinetic energy is given by:
T = 1/2 mv^2
so v = sqrt (2T/m)
They give you T and m. You've converted them to MKS, which is good. Now just plugnchug.
