In elastic collisions there is no loss of kinetic energyThis means that the total kinetic energy of the objects before the collision is the same as the total kinetic energy of the objects after the collision.Since kinetic energy Ek = ½mv2 given an initial speed of u and a final speed of v½mu2 = ½mv2(Momentum is always conserved in all types of collisions and explosions).
