Answer:
The answer is [tex] 1.956 \times 10^7\ m/s[/tex]
Explanation:
The amount of energy is not enough to apply the relativistic formula of energy [tex]E = mc^2[/tex], so the definition of energy in this case is
[tex]E = \frac{1}{2}m v^2[/tex].
From the last equation,
[tex]v= \sqrt{2E/m}[/tex]
where
[tex]E = 2 MeV = 3.204 \times 10^{-13} J[/tex]
and the mass of the neutron is
[tex]m = 1.675\times 10^{-27}\ Kg[/tex].
Then
[tex]v = 1.956 \times 10^7\ m/s[/tex]
the equivalent of [tex]0.065[/tex] the speed of light.
