The formula to calculate the Neutron Velocity (V_n) is:
\[ V_n = 1.383 \times 10^6 \times \frac{\sqrt{E}}{100} \]
Where:
A neutron's velocity is the measure of the speed of a neutron based on its mass and kinetic energy.
Let's say the neutron energy (E) is 25 eV. Using the formula:
\[ V_n = 1.383 \times 10^6 \times \frac{\sqrt{25}}{100} = 69,150 \text{ m/s} \]
So, the neutron velocity (V_n) is 69,150 m/s.
