The above homework question just sets the context for my question. I am not asking for a solution to this question

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, what is the magnitude of the relative velocity between the two particles after the collision?

How can kinetic energy after collision be more than initial kinetic energy in this particular case, where there is no disintegration of matter or something?

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) $\dfrac{v_0}{\sqrt2}$

(b) $\dfrac{v_0}4$

(c) $\sqrt2v_0$

(d) $\dfrac{v_0}2$
