In a collinear collision, a particle with an initial speed $\displaystyle v_{\mathrm{o}}$ strikes a stationary particle of the same mass. If the final total kinetic energy is $\displaystyle 50$% greater than the original kinetic energy, the magnitude of the relative velocity between the two particles, after collision, is :
Official answer
(2)
$\displaystyle \sqrt{2} v_{\mathrm{o}}$
