5.6 * 10^3 eV * (1.6*10^-19 Joules/ ev)
= 8.96 * 10^-16 Joules
if low compared to speed of light then
(1/2) m v^2 = (1/2)(1.67*10^-27 kg) v^2 = 8.96*10^-16
v^2 = 10.7 * 10^11 = 1.07 * 10^12
v = 1.03 * 10^6 m/s
that is far less than3*10^8 so not relativistic particularly
What is the speed of a proton whose kinetic energy is 5.6 keV ?
