A particle of mass $\displaystyle m$ moving in the $\displaystyle x$ direction with speed $\displaystyle 2 v$ is hit by another particle of mass 2m moving in the $\displaystyle y$ direction with speed $\displaystyle v$. If the collision is perfectly inelastic, the percentage loss in the energy during the collision is close to :
