In a collinear collision, a particle with an initial speed \( v_{0} \) strikes a stationary particle of the same mass. If the final total kinetic energy is \( 50 \% \) greater than the original kinetic energy, the magnitude of the relative velocity between the two particles after collision, is
(a) \( \frac{v_{0}}{4} \)
(b) \( \sqrt{2} v_{0} \)
(c) \( \frac{v_{0}}{2} \)
(d) \( \frac{v_{0}}{\sqrt{2}} \)
